lucene wildcard query with stop character

I assume you want all of your queries to function in this way?

If so, you could just translate the * character into a ? at search time,
which should give you the functionality you are asking for.

Unless I'm missing something.

well the ? would work if the length of each token be same.
however, instead of A>B>C I want tags that change dynamically from 1 to
unlimited length.

I just I could just pad every token to a normalized length such as
00000000...000A but i am hoping there is a better method.

if we could tell lucene to do it like in a regular expression until a > is
there to insert ??'s ...

Another way could be to do the regularexpression outside lucene, but then
still there is need for fetching the hits.

Best.

Hrm.. can we see a more specific example of the type of data you are
trying to query against here?

As i understand the question, this is a fairly classic hierarchical
organization of documents. Documents Foo>Bar>Baz and Foo>Bar>Bax are both
children of Document Foo>Bar ... Foo>Barber is their aunt (a sibling
document of Foo>Bar.

searching for doc:Foo>Bar>* will find all of the decendents of document
Foo>Bar ... but you want to just find the direct children (not hte grand
children)

the easiest way to tackled something like this is with multiple fields...

doc_path: Foo>Bar>Baz
parent: Foo>Bar

..then you can query for parent:"Foo>Bar" to find all of the direct
children, or doc:Foo>Bar>* to find all decendents.

i typically use an "ancestors" field, where every ancestor in the "family
tree" is enumerated as a seperate field value, so that i'm not dependent
on prefix queries to do "decendents" queries like that....

doc_path: Foo>Bar>Baz
parent: Foo>Bar
ancestor: Foo>Bar
ancestor: Foo
