I already have some documents indexed using more NumericFields per document.
Now I want to search the documents that have all fields from <-3,+3> interval e.g.:

query: n1=7,n2=10,n3=12 – and the search should return all documents that have numbers from intervals: n1=<4,10>,n2=<7,13>,n3=<9,15>.

Question: what analyzer do I need, how to write a query, what searcher to use?

It’s an assignment, so I can’t use any other tools that are built for searching in ranges, have to use Lucene.

Thanks

    Is does not require any analzer or searcher,
    just need to ensure building the correct query like :-

    Example 1: Or (meaning match either one of the conditions)

    n1:(4 10) n2:(7 13) n3:(9 15)

    Example 2: And (meaning all three parenthesis must matched)

    +n1:(4 10) +n2:(7 13) +n3:(9 15)

    Example 3: Range (your question sounds like a range search)

    n1:[4 TO 10] n2:[7 TO 13] n3:[9 TO 15]

    Example 4: And range

    +n1:[4 TO 10] +n2:[7 TO 13] +n3:[9 TO 15]
