Hi I'm use latest version of ES(0.15) and had some problems with highlighting. Data : { ... streamType: Feed message: bla bla bla post bla bla 1 bla tenantId: 1 ... } Example of query: query : { bool : {must : [ {field: {streamType: {query: "Feed"}}}, {wildcard : { message : "_post_" }}, {term : { tenantId : "1" }}, {range : {postDate : {...}}} ]}}, highlight : {" "pre\_tags" : ... "post\_tags" : ... "fields" : {"message" : {"fragment\_size" : 200, "number\_of\_fragments" : 1}" } } Result: bla bla bla post bla bla \ 1 bla As you can see in highlight fields only "message" marked as highlighted, but in results some items highlighted for field tenantId. Any ideas how to resolve this? Thanks. ---

It looks to me like the '1' is being highlighted because you specify {tenantId: 1} as part of the query, when actually you want it to be applied as a filter. I've posted a version using a query of type 'filtered' which highlights correctly: [ES: demo for highlight bug · GitHub](https://gist.github.com/837120#comments) clint ---

Filters are very fast indeed clint ---
