Full text search : search phrase in text

Elastic Stack Elasticsearch
1

Hi
i am using elasticsearch for storing some text fields.
while using white space tokenizer , the text is divided into tokens based
on the white space separation between them , and is searchable by token
based search only .

but , m not able to do some phrase search , like i am indexing ,
" ELASTIC SERVER FULL TEXT SEARCH"
i am able to search for any of the tokens in the above text , but not on
any continuous phrase like, "ELASTIC SERVER" .

which , analyzer(tokenizer /tokenfilter) combination should be used to
search for a phrase in the full text search.
Could somebody please help me resolve the issue ?

Thanks
Tarang Dawer

i have tried using the field query , but it returns results based on token
match ,
like for example , i have documents like "1. THIS IS ELASTICSEARCH"
"ELASTICSEARCH IS AWESOME"

if i search for IS ELASTICSEARCH , both of my documents are returned as a
search hit .

is there some way , or elasticsearch/lucene stores/maintains a certain
positioning or ordering system , so that only THIS IS ELASTICSEARCH is
returned ?

Also please suggest tokenizer/analyzer for the document , to be searchable
in this way ?

Thanks

There are quite a few options but the easiest is to use the Match phrase
query: Elasticsearch Platform — Find real-time answers at scale | Elastic

You can use a QueryStringQuery with a quoted phrase in the query string or
you can enable the auto_generate_phrase_queries option. There are some
indexing techniques using Shingles as well but that is overkill for what
you want to do.
