relevance

问题 I have an index containing 3 documents. { "firstname": "Anne", "lastname": "Borg", } { "firstname": "Leanne", "lastname": "Ray" }, { "firstname": "Anne", "middlename": "M", "lastname": "Stone" } When I search for "Anne", I would like elastic to return all 3 of these documents (because they all match the term "Anne" to a degree).

问题 I am using the below code for example: SELECT *, (MATCH (`wm`, `locn`, `gns`) AGAINST('foot locker')) AS score FROM `example_table` WHERE MATCH (`wm`, `locn`, `gns`) AGAINST('foot locker')) order by score DESC; However even though EXACT matches exist in the wm column, the EXACT match doesn't appear untiil the 8th result. The ones ahead of it all have the phrase too, but also some following text. I checked the locn , gns fields to see how they compared and nothing really stands out that should

问题 I have a Solr index with about 2.5M items in it and I am trying to use an ExternalFileField to boost relevancy. Unfortunately, it's VERY slow when I try to do this, despite it being a beefy machine and Solr having lots of memory available. In the external file I have contents like: 747501=3.8294805903e-07 747500=3.8294805903e-07 1718770=4.03292174724e-07 1534562=3.8294805903e-07 1956010=3.8294805903e-07 747509=3.8294805903e-07 747508=3.8294805903e-07 1718772=3.8294805903e-07 1391385=3

问题 We are using Solr 5. We are able to apply sorting on display order field in to Solr query and it works fine. We have certain results which are elevated and will always want them first. If we remove the sorting, the elevation works fine. However, we are unable to get both of them work together. We want to first list elevated results in the top and then other results based on the display order field. However, we are unable to find how to do this. Any help will be appreciated. Thanks in advance.

问题 To achieve some degree of fault tolerance with Solr I have started to use the NGramFilterFactory . Here are the intersting bits from the schema.xml : <field name="text" type="text" indexed="true" stored="true"/> <copyField source="text" dest="text_ngram" /> <field name="text_ngram" type="text_ngram" indexed="true" stored="false"/> <fieldType name="text_ngram" class="solr.TextField" positionIncrementGap="100"> <analyzer> <tokenizer class="solr.KeywordTokenizerFactory" /> <filter class="solr
