Hi
I'm constructing a BooleanQuery with an optional filter query and a
mandatory content query, plus some optional boost queries.
In effect, what I am doing is implementing this shorthand:
BooleanQuery.Builder qb = new BooleanQuery.Builder();
if (filter) {
qb.add(filterquery,
refine sort with this numeric value.

Hi, I've hit a wall here.
In brief, users search a library of documents. Every indexed document has a
version number field which is always populated for release notes, sometimes
for other docs. Every document also has a category field which is how
release notes are identified, among other
/TestMatchHighlighter.java#L241-L269
If things work for you then no rush to switch over - it's yet another option to
use.

Sorry I apologize for this being a bit long and for explaining the problem
at the very bottom after all the background, rather than starting with it at

Hi
I'm currently using Lucene 8-6.3, and indexing a few thousand documents.
Some of these documents need to be prioritised in the search results, but
not by too much; e.g. an exact phrase match in a normal document still needs
to top the rankings ahead of a priority document that just matches

Hello Trevor.
Can you help me better understand this approach? If we have a text "wifi

Hi Anh
The two links Michael shared relate to questions I asked when I was trying to
get synonym matching with our application.
I really do have multi-term synonym matching working at this point; there's
always scope for improvement of course but with the hints suppled in those
threads I was
I am indexing some technical documentation and have been trying to add
synonym matching to the searches. Actually I am adding the synonyms at index
time so that any synonyms match at search time.
a. Simple synonyms (wordA = wordB) are working just fine.
b. Multiple synonyms
Just to confirm, escaping the spaces in synonym table construction, query
construction, or both, does not solve the problem.

Hello,
just a guess, have you tried escaping the space in your multi-word terms with

I have technical data which I am querying with Lucene; one of the features

I am using Lucene 8.6.3 in an application which searches a library of

In a prototype application I build a Lucene index with a single process and
query it with another. Every operation is a new process. When the data
changes I simply recreate the index and future searches pick up the new
index. Of course performance is sub-optimal.

Hi
You want to write your own analyzer which does not lowercase terms and which
splits terms at non-alpha or non-alphanumeric characters. You'd use the same
analyzer for indexing and for searching. Thus when building the index S.O.S is
indexed as the five terms S . O . S and if you search for

Sorry in advance for writing a small novel.
Background: I am indexing and searching technical reference documents, so
the standard language analyzers aren't appropriate. For example, the content
needs to be indexed so that a search for total matches total value,
total[value], and total(value),

the source code, it is old and built on Lucene 3.5 so would need quite some
upgrade.

Hello, I'd better begin by identifying myself as a newbie.
I am investigating using Lucene as a search tool for a library of technical
documents, much of which consists of pieces of source code and discussion of
the content.
The standard analyzer does an adequate job with normal text but
