I am configuring standard tokenizer and lowercase and I am able to perform good search, like words between sentence, key value pair. # Index Settings index: analysis: analyzer: # set standard analyzer with no stop words as the default for both indexing and searching default\_index: type: custom tokenizer: standard filter: [standard,lowercase] My concern is that When I search A=B then get the result for A, B and A=B three of them, IF i make it to whitespace then it solves my problem but not able to search words between the sentences. How can I keep that A=B should not tokenize A=B and retains as it is, and want to retain the Index setting -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

You can use a the pattern tokenizer. If you configure it with the same delimiters as the standard tokenizer with the exception of '=', your queries should work. -- Ivan On Sun, Dec 15, 2013 at 1:30 AM, deep saxena [sandy100ster@gmail.com](mailto:sandy100ster@gmail.com) wrote: > I am configuring standard tokenizer and lowercase and I am able to > perform good search, like words between sentence, key value pair. > > # Index Settings > > index: > analysis: > analyzer: > # set standard analyzer with no stop words as the default for both > indexing and searching > default\_index: > type: custom > tokenizer: standard > filter: [standard,lowercase] > > My concern is that When I search A=B then get the result for A, B and A=B > three of them, IF i make it to whitespace then it solves my problem but not > able to search words between the sentences. > How can I keep that A=B should not tokenize A=B and retains as it is, and > want to retain the Index setting > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > To view this discussion on the web visit > [https://groups.google.com/d/msgid/elasticsearch/3b253330-0d6d-4a36-b2d0-6c63f08522d1%40googlegroups.com](https://groups.google.com/d/msgid/elasticsearch/3b253330-0d6d-4a36-b2d0-6c63f08522d1%40googlegroups.com) > . > For more options, visit [https://groups.google.com/groups/opt\_out](https://groups.google.com/groups/opt_out). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
