Btw. I tried the wildcard since I found something on google, which noted
wildcards together with StartsWith queries.

Hi Ian,
no the wild cards should not be necessary. That was just the last try
out of some. I now the exact content of both fields in my range query.
The case is as the java code found it, but the analyzer will lowercase
it anyhow. I'm trying the SimpleAnalyzer since all other seem to ommit
single char terms.
name:("A Balladeer") (translated to name:("a balladeer") by the
analyzer gives me the doc I expect with doc Id 13002.
name:("A Perfect Circle") gives me as excpected doc Id 35833.
However:
name:["A Balladeer" TO "A Perfect Circle"] gives zero results. Tried
it also with braces around the term and such stupid things, even if
they shouldn't be needed in a range query.
I'm kinda clueless.
Cheers,
Thomas

Hi
Are you sure your range queries should have wild card asterisks on the
end? Looks odd to me and I don't know what the effect would be.
I'd also prefer everything in lower case but maybe you've got the
right analyzers being used consistently in indexing and searching
chains.

Hi all,
I need to replace some db queries with lucene due to response time
issues
for sure. In this special case I need to do a range query on a field
and a
prefix query. I'm trying to prepare and try my query in luke with no
success
before migrating it to java.
I need to find all names starting with for example "A Balladeer" to "A
Perfect Circle" in the name field. The sort field is sortName (same
content
as name, but untokenized for sorting).
I tried the following in luke which should give me a few hundred docs:
name:["A Balladeer*" TO "A Perfect Circle*"] - 0 results, also there
should
be some
name:["A Balladeer*" TO "B*" - >10k results, but also returns
results which
have a string in the middle or end starting with A
I tried using sortName (untokenized) field instead:
sortName:["A Balladeer*" TO "B*" - 25 results, all starting with A*
(guess
since it's untokenized), but far less than expected again
Tried a couple of more (stupid) things with little success. I googled
around, but I'm kinda stuck here. So I'm asking the list. How can I
search
all name/sortName fields in a range between "A Balladeer*" TO "A
Perfect
Circle*" and get only terms back which are starting with that terms? Is
there a way to accomplish that in Java and try it in luke?
And is there a way to sort resultsets in luke?
Cheers,
Thomas
