the postings lists and per-document values in the fieldType element |
|
(postingsFormat/docValuesFormat). Note that most of the alternative implementations |
|
are experimental, so if you choose to customize the index format, its a good |
|
idea to convert back to the official format e.g. via IndexWriter.addIndexes(IndexReader) |

A possible optimization that attempts to use a filter to |

score, then the filterCache will be checked for a filter |
|
matching the query. If found, the filter will be used as the |
|
source of document ids, and then the sort will be applied to |
|
that. |
|
|

For most situations, this will not be useful unless you |

frequently get the same search repeatedly with different sort |

are collected. For example, if a search for a particular query |
|
requests matching documents 10 through 19, and queryWindowSize is 50, |

then documents 0 through 49 will be collected and cached. Any further |

|
|
|
This section contains instructions for how the SolrDispatchFilter |

should behave when processing requests for this SolrCore. |
|
|
|
handleSelect is a legacy option that affects the behavior of requests |
|
such as /select?qt=XXX |
|
|
|
handleSelect="true" will cause the SolrDispatchFilter to process |
|
the request and dispatch the query to a handler specified by the |
|
"qt" param, assuming "/select" isn't already registered. |
|
|
|
handleSelect="false" will cause the SolrDispatchFilter to |
|
ignore "/select" requests, resulting in a 404 unless a handler |
|
is explicitly registered with the name "/select" |
|
|
|
handleSelect="true" is not recommended for new users, but is the default |
|
for backwards compatibility |
|
--> |
|
<requestDispatcher handleSelect="false" > |
|
<!-- Request Parsing |
|
|
|
These settings indicate how Solr Requests may be parsed, and |
|
what restrictions may be placed on the ContentStreams from |
|
those requests |
|
|
|
enableRemoteStreaming - enables use of the stream.file |
|
and stream.url parameters for specifying remote streams. |
|
|
|
multipartUploadLimitInKB - specifies the max size (in KiB) of |
|
Multipart File Uploads that Solr will allow in a Request. |
|
|
|
formdataUploadLimitInKB - specifies the max size (in KiB) of |
|
form data (application/x-www-form-urlencoded) sent via |
|
POST. You can use POST to pass request parameters not |
|
fitting into the URL. |
|
|
|
addHttpRequestToContext - if set to true, it will instruct |
|
the requestParsers to include the original HttpServletRequest |
|
object in the context map of the SolrQueryRequest under the |
|
key "httpRequest". It will not be used by any of the existing |
|
Solr components, but may be useful when developing custom |
|
plugins. |
|
|
|
*** WARNING *** |
|
The settings below authorize Solr to fetch remote files, You |
|
should make sure your system has some authentication before |
|
using enableRemoteStreaming="true" |
|

<!-- HTTP Caching |
|
|
|
Set HTTP caching related parameters (for proxy caches and clients). |

|
--> |
|
<httpCaching never304="true" /> |
|
<!-- If you include a <cacheControl> directive, it will be used to |
|
generate a Cache-Control header (as well as an Expires header |
|
if the value contains "max-age=") |
|
|
|
By default, no Cache-Control header is generated. |
|
|
|
You can use the <cacheControl> option even if you have set |
|
never304="true" |
|
--> |
|
<!-- |
|
<httpCaching never304="true" > |
|
<cacheControl>max-age=30, public</cacheControl> |

|
<!-- To enable Solr to respond with automatically generated HTTP |
|
Caching headers, and to response to Cache Validation requests |
|
correctly, set the value of never304="false" |
|
|
|
This will cause Solr to generate Last-Modified and ETag |
|
headers based on the properties of the Index. |
|
|
|
The following options can also be specified to affect the |
|
values of these headers... |
|
|
|
lastModFrom - the default value is "openTime" which means the |
|
Last-Modified value (and validation against If-Modified-Since |
|
requests) will all be relative to when the current Searcher |
|
was opened. You can change it to lastModFrom="dirLastMod" if |
|
you want the value to exactly correspond to when the physical |
|
index was last modified. |
|
|
|
etagSeed="..." is an option you can change to force the ETag |
|
header (and validation against If-None-Match requests) to be |
|
different even if the index has not changed (ie: when making |
|
significant changes to your config file) |
|
|
|
(lastModifiedFrom and etagSeed are both ignored if you use |
|
the never304="true" option) |

<!-- Request Handlers |
|
|
|
http://wiki.apache.org/solr/SolrRequestHandler |
|
|
|
Incoming queries will be dispatched to a specific handler by name |
|
based on the path specified in the request. |
|
|
|
Legacy behavior: If the request path uses "/select" but no Request |
|
Handler has that name, and if handleSelect="true" has been specified in |
|
the requestDispatcher, then the Request Handler is dispatched based on |
|
the qt parameter. Handlers without a leading '/' are accessed this way |
|
like so: http://host/app/[core/]select?qt=name If no qt is |
|
given, then the requestHandler that declares default="true" will be |
|
used or the one named "standard". |
|
|
|
If a Request Handler is declared with startup="lazy", then it will |
|
not be initialized until the first request that uses it. |
|
|

<!-- SearchHandler |

|

In this example, the facet.field and facet.query params would |

|
|
|
http://wiki.apache.org/solr/AnalysisRequestHandler |
|
|
|
An analysis handler that provides a breakdown of the analysis |

process of provided documents. This handler expects a (single) |
|
content stream with the following format: |
|
|
|
<docs> |
|
<doc> |
|
<field name="id">1</field> |
|
<field name="name">The Name</field> |

<field name="text">The Text Value</field> |
|
</doc> |
|
<doc>...</doc> |
|
<doc>...</doc> |
|
... |
|
</docs> |
|
|
|
Note: Each document must contain a field which serves as the |
|
unique key. This key is used in the returned response to associate |

|
|
|
http://wiki.apache.org/solr/SolrReplication |
|
|
|
It is also necessary for SolrCloud to function (in Cloud mode, the |
|
replication handler is used to bulk transfer segments when nodes |
|
are added or need to recover). |

To enable simple master/slave replication, uncomment one of the |
|

also need to fill in the masterUrl to point to a real machine. |

<!-- Search Components |
|
|
|
Search components are registered to SolrCore and used by |
|
instances of SearchHandler (which can access them by name) |
|
|
|
By default, the following components are available: |
|
|
|
<searchComponent name="query" class="solr.QueryComponent" /> |
|
<searchComponent name="facet" class="solr.FacetComponent" /> |
|
<searchComponent name="mlt" class="solr.MoreLikeThisComponent" /> |
|
<searchComponent name="highlight" class="solr.HighlightComponent" /> |
|
<searchComponent name="stats" class="solr.StatsComponent" /> |
|
<searchComponent name="debug" class="solr.DebugComponent" /> |
|
|
|
Default configuration in a requestHandler would look like: |
|
|
|
<arr name="components"> |
|
<str>query</str> |
|
<str>facet</str> |
|
<str>mlt</str> |
|
<str>highlight</str> |
|
<str>stats</str> |
|
<str>debug</str> |
|
</arr> |
|
|
|
If you register a searchComponent to one of the standard names, |
|
that will be used instead of the default. |
|
|
|
To insert components before or after the 'standard' components, use: |
|
|
|
<arr name="first-components"> |
|
<str>myFirstComponentName</str> |
|
</arr> |
|
|
|
<arr name="last-components"> |
|
<str>myLastComponentName</str> |
|

|
|
NOTE: The component registered with the name "debug" will |
|
always be executed after the "last-components" |

<!-- Language identification |
|
|
|
This example update chain identifies the language of the incoming |
|
documents using the langid contrib. The detected language is |
|
written to field language_s. No field name mapping is done. |
|
The fields used for detection are text, title, subject and description, |
|
making this example suitable for detecting languages form full-text |
|
rich documents injected via ExtractingRequestHandler. |
|
See more about langId at http://wiki.apache.org/solr/LanguageDetection |

<!-- Response Writers |
|
|
|
http://wiki.apache.org/solr/QueryResponseWriter |
|
|
|
Request responses will be written using the writer specified by |
|
the 'wt' request parameter matching the name of a registered |
|
writer. |
|
|
|
The "default" writer is the default and will be used if 'wt' is |
|
not specified in the request. |
|
--> |
|
<!-- The following response writers are implicitly configured unless |
|
overridden... |
|

<!-- Query Parsers |
|
|
|
http://wiki.apache.org/solr/SolrQuerySyntax |
|
|
|
Multiple QParserPlugins can be registered by name, and then |
|
used in either the "defType" param for the QueryComponent (used |
|
by SearchHandler) or in LocalParams |
|
--> |
|
<!-- example of registering a query parser --> |
|
<!-- |
|
<queryParser name="myparser" class="com.mycompany.MyQParserPlugin"/> |

|
|
|
<!-- Function Parsers |
|
|
|
http://wiki.apache.org/solr/FunctionQuery |
|
|
|
Multiple ValueSourceParsers can be registered by name, and then |
|
used as function names when using the "func" QParser. |
|
--> |
|
<!-- example of registering a custom function parser --> |
|
<!-- |
|
<valueSourceParser name="myfunc" |
|
class="com.mycompany.MyValueSourceParser" /> |

<!-- Document Transformers |
|
http://wiki.apache.org/solr/DocTransformers |
|
--> |
|
<!-- |
|
Could be something like: |
|
<transformer name="db" class="com.mycompany.LoadFromDatabaseTransformer" > |
|
<int name="connection">jdbc://....</int> |
|
</transformer> |
|
|
|
To add a constant value to all docs, use: |
|
<transformer name="mytrans2" class="org.apache.solr.response.transform.ValueAugmenterFactory" > |
|
<int name="value">5</int> |
|
</transformer> |
|
|
|
If you want the user to still be able to change it with _value:something_ use this: |
|
<transformer name="mytrans3" class="org.apache.solr.response.transform.ValueAugmenterFactory" > |
|
<double name="defaultValue">5</double> |
|
</transformer> |
|
|
|
If you are using the QueryElevationComponent, you may wish to mark documents that get boosted. The |
|
EditorialMarkerFactory will do exactly that: |
|
<transformer name="qecBooster" class="org.apache.solr.response.transform.EditorialMarkerFactory" /> |
