Range queries in successive positions
Hi,
I'm new to Lucene. I'm indexed some documents with Lucene and need to sanitize it to ensure
that they do not have any social security numbers (3-digits 2-digits 4-digits).
(How) Can I write a query (with the QueryParser) that searches for this pattern?
e.g. I can do [000 to 999] or [00 to 99] or [0000 to 9999], but this causes hits with any 2, 3 or 4 digit number.
Something like "[000 to 999] [00 TO 99] [0000 TO 9999]", I get no hits at all.
Is this possible with the default QueryParser?
Or is there some other programmatic way to do it?
thanks,
Sandeep

Or take a look at search.regex.RegexQuery contrib module. You won't
be able to use that via QueryParser either.
It might make more sense to do the sanitizing before indexing rather than after.

The programmatic way is to use SpanMultiTermQueryWrapper around each
RangeQuery and then SpanNearQuery around the lot.
The default QueryParser probably can't do it. I believe someone was
enhancing it for wildcards but I'm not sure if range queries were
included in all that.
