I'm working on a super fast completion engine using ES. I'm using a wildcard term so everything is OK when I type one term. But if I start typing a sentence (like the title of the conversation I want to read), the query does not return anything. I've read that I should mark the searched field as "not\_analyzed" but I don't figure out how to do that. thx ---

Hi, Check the "index":"not\_analyzed" attribute/value in mappings, for example here: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/mapping/core-types.html) May be you should also consider using prefix query: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/query-dsl/prefix-query.html) [http://www.elasticsearch.org/guide/reference/query-dsl/prefix-query.html](http://www.elasticsearch.org/guide/reference/query-dsl/prefix-query.html) Regards, Lukas On Fri, Feb 25, 2011 at 10:58 AM, alheim [alexheimburger@gmail.com](mailto:alexheimburger@gmail.com) wrote: > I'm working on a super fast completion engine using ES. > > I'm using a wildcard term so everything is OK when I type one term. > > But if I start typing a sentence (like the title of the conversation I > want to read), the query does not return anything. > > I've read that I should mark the searched field as "not\_analyzed" but > I don't figure out how to do that. > > thx ---

I tried to use "index":"not\_analyzed". Not better. Imagine that I want to index a document with a title "I want to become a ES expert" If I search "I want" , there should be a hit. If I search "beco", there should be a hit and If I search "a ES expert", there should be a hit. How do I need to configure the field ? thanks for your help.

Thx for help. I followed these steps : Into config/elasticsearch.yml, add a custom analyzer index: analysis : analyzer : lowercase\_keyword : type : custom filter : [lowercase] tokenizer : keyword Call the URL : curl -XPUT '[http://localhost:9200/devalex10/post/\_mapping](http://localhost:9200/devalex10/post/_mapping)' -d ' { "post" : { "properties" : { "title" : {"type":"string", "analyzer":"lowercase\_keyword"} } } } IMPORTANT : if the index already exist, one should get an error saying that there is a merge conflict. Do not attempt to use the ignore\_merge parameter which will just ignore the new analyzer. The solution is to scratch the index et index again. Any other idea ?

You can do a combination of several options. For example, use a multi field mapping that have it both not analyzed, analyzed once with ngrams, and another option to analyze it with shingles ([Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/index-modules/analysis/shingle-tokenfilter.html)). Then, you can query those fields in a single search request, either using several queries, or using a query string that runs against those.

Yes, it will be indexed several times with different "term" combinations.
