curl -XPUT localhost:9200/_cluster/settings -d '{"transient":{"cluster.routing.allocation.disable_allocation": true}}'

Can be used without specifying an index against one of the many built in analyzers:

curl -XGET 'localhost:9200/_analyze?analyzer=standard' -d 'this is a test'

Or by building a custom transient analyzer out of tokenizers, token filters and char filters. Token filters can use the shorter filters parameter name:

curl -XGET 'localhost:9200/_analyze?tokenizer=keyword&filters=lowercase' -d 'this is a test'

curl -XGET 'localhost:9200/_analyze?tokenizer=keyword&token_filters=lowercase&char_filters=html_strip' -d 'this is a <b>test</b>'
It can also run against a specific index:
