: Subject: Percolate feature? can you give a more concrete, realistic example of what you are trying to do? your synthetic hypothetical example is kind of hard to make sense of.
your Subject line and comment that the "percolate" feature of elastic search sounds like what you want seems to have some lead people down a path of assuming you want to run these types of queries as documents are indexed -- but that isn't at all clear to me from the way you worded your question other then that. it's also not clear what aspect of the "results" you really care about -- are you only looking for the *number* of documents that "match" according to your concept of matching, or are you looking for a list of matches? what multiple documents have all of their terms in the query string -- how should they score relative to eachother? what if a document contains the same term multiple times, do you expect it to be a match of a query only if that term appears in the query multiple times as well? do you care about hte ordering of the terms in the query? the ordering of hte terms in the document? Ideally: describe for us what you wnat to do, w/o assuming solr/elasticsearch/anything specific about the implementation -- just describe your actual use case for us, with several real document/query examples. https://people.apache.org/~hossman/#xyproblem XY Problem Your question appears to be an "XY Problem" ... that is: you are dealing with "X", you are assuming "Y" will help you, and you are asking about "Y" without giving more details about the "X" so that we can understand the full issue. Perhaps the best solution doesn't involve "Y" at all? See Also: http://www.perlmonks.org/index.pl?node_id=542341 -Hoss
