Hi all,
I'm using Lucene as a fulltext search engine since a year now and this one
works well for this.
Now, I want to add to my application search capability like : aField greater
than 10 , aField between 10 and 20.
For this, I used RangeQuery (aField:[10 TO 20] for exemple) and I received all
documents with field between these 2 values.
All was perfect before... benchs. These one were poor. I received results after
dozens of seconds.
Here is reasons of this :
Firstly, I don't know min or max values for my field so a request can be
aField:[0 TO 1000000].
If I understand, this request is tranform in a BooleanQuery with one million of
TermQuery separated by OR.
Secondly, to perform greater than or lower than request, I wanted to use
RangeQuery with Integer.MAX_VALUE (for greater than)
or Integer.MIN_VALUE (for lower than). If I understand always, this RangeQuery
would be transform in a BooleanQuery with many
millions of TermQuery.
How to perform this kind of searchs (with another Lucene use, with anoter
solution, ...) ?
Many thanks for your comments.
