The ~2 syntax, when not attached to a phrase query (quotes) is the way you express a fuzzy query. If it's attached to a query in quotes, then it is a proximity query. I'm not sure whether it means something different when it's attached to a query clause in parentheses, someone with more knowledge will need to comment. > How can I achieve following? > "boost(+((fl:java fl:book)),int(val))" > > The reason being the ANDed and ORed queries both returns the same number of > documents.

Normally I would say that if you get the same number of documents with both "AND" & "OR" then it means that every document that contains "java" also contains "book" ... but since you are running version 5.5.0, there is a bug report that describes what you are seeing: https://issues.apache.org/jira/browse/SOLR-8812 Thanks, Shawn
