elasticsearch.rb

client = ElasticWrapper::Session.new.client

client.search(index: 'test', type: 'contacts', body: body)

body = { query: { bool: { filter: { term: { name: 'lachlan' } } } } }
=>
[{ 
  "_index"=>"test",
  "_type"=>"contact",
  "_id"=>"1",
  "_score"=>1.0,
  "_source"=>{
    "id"=>2157,
    "name"=>"Lachlan Priest"
  }
}]
body = { query: { bool: { filter: { term: { name: 'Lachlan' } } } } }
=> 
[]

Thanks! This was essentially what I was looking for, I've ended up using the keyword tokenizer (though I might just drop this, as it's essentially the same as not_analyzed) and a lowercase filter to allow for case insensitive search.

I ended up doing a static mapping for as many fields as I know in advance and will just look into again every month or so and see if I find any recurring fields in mappings that I didn't define yet.

Thanks for the post - I think the best piece of advice that someone gave was that the ES docs are not really reference docs, they are more like a tutorial. They are much better if you read them like a book and follow the pages; after that everything became a lot clearer.

Again, thank you, this has been really helpful.
