If I search for "liz" I need an exact match of "liz" to score higher than "lizz" Can I do this all in one query or do I need to run a separate query to look for an exact match? --chad -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I would expect it to do this automatically, because "liz" has fewer tokens than "lizz". However, to ensure that it works the way you want, you can index the field as a multi-field, using (eg) the standard analyzer on the main field, and your edge-ngrams on another field. The use a bool query which matches against both fields - you'll find docs that match the ngrams, but docs with exact matches will be boosted by the clause on the main field. clint On 21 May 2013 19:39, Chad Kouse [chad.kouse@gmail.com](mailto:chad.kouse@gmail.com) wrote: > If I search for "liz" I need an exact match of "liz" to score higher than > "lizz" > > Can I do this all in one query or do I need to run a separate query to > look for an exact match? > > --chad > > -- > 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). > 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.

Hi Clint, We are encountering the same issue. This sounds like a bug. Should we file a ticket against ES?

I was also expecting this to work without using multi-field. Am I missing something? ---

It's 2017, and I'm still have the same problem? Did anyone figure this out without using multi-field? Or is that the only way? I'd really love to know! Thanks in advance! ---
