The cross_field type tries to solve these problems at query time by taking a term-centricapproach. It first analyzes the query string into individual terms, then looks for each term in any of the fields, as though they were one big field.
So when it analyzes the query into individual terms, which analyzer and filter dows it use ? Can we configure it with a specific analyzer and filter at index time on the fields in mapping ?
I think we can now use multi-match as a replacement for query string ? Earlier multi-match will match a document only if the query string after analysis is present entirely in one field but now we can search for a document where a document consists of all the query terms, no matter if it is present in one field or a combination of fields. Am I correct ?
