Search a list of words and returned order

["Croci Francesco Luigi (ID SWS)" <fc...@id.ethz.ch>]

When I search  for a list of words, per default Solr uses the OR operator.

In my case I index (pdfs) files. How/what can I do so that when I search the index for a list of words, I get the list of documents ordered first by  the ones that have all the words in them?

Thank you
Francesco

Hi;

The documents with more words that matched the query will be higher in the
result list than those that have fewer words that matched the query. If you
want to have documents that have all th equery words in their fields at the
top of the results list you can try that:

Define a query with a mm of 1 and define a boost query with the help of
dereferencing as like:

{!edismaxqf=$boostQueryQf mm=100% v=$mainQuery}"^100000

You can check the Apache Solr CookBook page 296. If you have any problems I
can help you.

Thanks;

Generally, the documents containing more of the terms should score higher 
and be returned first, but "relevancy" for some terms can skew that 
ordering, to some degree. What specific use cases are failing for you?

You can always add an additional optional subquery which is the AND of all 
terms and has a significant boost:

q=see spot run (+see +spot +run)^10
