Instead of specifying a percentage or number of query terms must match tokens in a field, I'd like to do the opposite -- specify how much of a field must match a query.
The problem I'm trying to solve is to boost document titles that closely match the query string. If a title looks something like *Title: *[solr] [the] [worlds] [greatest] [search] [engine] I want to be able to specify how much of the field must match the query string. This differs from normal mm. Normal mm specifies a how much of the query must match a field. As an example, with this title, if I use normal mm=100% and perform the following query: mm=100% q=solr This will match the title above, as 100% of [solr] matches the field What I really want to get at is a reverse mm: Rmm=100% q=solr The title above will not match in this case. Only 1/6 of the tokens in the field match the query. However an exact search would match: Rmm=100% q=solr the worlds greatest search engine Here 100% of the query matches the title, so I'm good. Is there any way to achieve this in Solr? -- Doug Turnbull Search & Big Data Architect OpenSource Connections <http://o19s.com>
