Hi Kelvin and Matthias,
Thanks a lot for your direction. I made QueryFilter
and IndexFilter for price field. Here is feedback from
running bin/nutch net.nutch.searcher.Query
Parsed: price:"f0000000000t1000000000"
Translated: +price:[0000000000 TO 1000000000]
It looks like it is translated into range query.
However, when I type this query into search box in
Tomcat, it doesn't work. I wonder if I need turn on
something in JSP pages or I may use wrong index type
in the index filter.
Here is a sentence I used in the indexFilter class
doc.add(Field.UnStored("price",PriceString));
Is that wrong type I used? I also tried
"Field.Keyword", it doesn't work either.
The following are prices I indexed
0000069900
0005450000
0000099900
0000839000
0000969000
0000087400
0001249500
0000019000
0001200000
0000019900
0000000000
0000089900
0000574900
0000000000
0000099900
0000399900
0000050000
0000089900
0000025000
0000074900
0000019900
0000079400
0000049900
0000099900
0000027000
it is supposed to return something, but it deosn't.
Could you please help out?
Thanks in advance.
