SOLR 5.1 中的精确匹配

Question

I have setup Solr 5.1.0 with proper data importation from MYSQL database. It is working good.

But I want exact match results or relevant to that only.

like,

Dancers in Mumbai

It gives all results which contains "dancers + mumbai" and only "dancers" + only "mumbai" keywords. I want result which must contains only "dancers + mumbai" not others.

Answer 1

This is not a complete answer, but it's the direction I'm trying to take with a similar problem. Comments are very welcome.

Step 1: Implement multiple Solr cores, core 1 is "jobs" (dancers/lawyers/etc), and core 2 is "cities" (mumbai/chennai/etc).

Step 2: Query each core for exact matches, so implement the KeywordTokenizerFactory on the relevant field to find exact matches only. This will give you all the matches accross cores (eg jobs: dancers and cities:mumbai).

Step 3: Perform your general query using EDisMax for a user-friendly search (eg searching for "dancers in mumbai" accross many fields), and use the boost field to boost the jobs/cities found in the earlier query.

I would love to know if there is a better way of doing something this elaborate, but I have not found it yet. Hope it helps.

Answer 2

Using required terms like: +dancers +mumbia

Or a phrase query: "dancers in mumbia"

Would work.

You can also set the default operator for your query to be "AND", using the q.op parameter .
