searching/filtering by field's value length

[Federico Schroder <fs...@runway10.com>]

Hello,
I need some help doing a search.
Say I have a really simple document structure, just 1 field, labeled name.
I need to retrieve all the names whose length is more or less than a
specified value. By length I mean String.length().
A range filter seems close in concept, but I couldn't find a good example to
write my specific case.
Thanks for the help,
Federico

Store the string length as a NumericField with each document and use
NumericRangeQuery. There are examples in the javadocs.
