Lucene and Advanced Search

[netos]

hi all.

i have changed the advanced search screen so that i can search for some custom properties of mine in a range search (i.e. from x to y).

i thought it worked fine, i used the same addRangeAttribute method similiar to what is done with dates. the problem is that i found out that lucene searches the property lexicographically and as a result 20 becomes bigger than 108 for example…

does it help if i change the custom property from text to int or long? do i have to go through the entire DB and change the representation there also? can i just tell lucene i am referring to numbers? any idea?

help…

thx, netanel

I haven't used the "advanced search" screen and may be off tpoic but thought I'd have a go cause this forum can take a while to get an answer.

I have been using the Lucene proximity search to solve some problems but the following URL give you the full capability of the Lucene syntax.

Hi

Numbers are only treated correctly for numeric types, not text.
