|
|
<p>Although Lucene provides the ability to create your own
|
|
queries through its API, it also provides a rich query
|
|
language through the Query Parser.</p>
|
|
<p>This page
|
|
provides syntax of Lucene's Query Parser, a lexer which
|
|
interprets a string into a Lucene Query using JavaCC.</p>
|
|
<p>
|
|
Before choosing to use the provided Query Parser, please consider the following:
|
|
<ol>
|
|
<li>If you are programmatically generating a query string and then
|
|
parsing it with the query parser then you should seriously consider building
|
|
your queries directly with the query API. In other words, the query
|
|
parser is designed for human-entered text, not for program-generated
|
|
text.</li>
|
|
|
|
<li>Untokenized fields are best added directly to queries, and not
|
|
through the query parser. If a field's values are generated programmatically
|
|
by the application, then so should query clauses for this field.
|
|
An analyzer, which the query parser uses, is designed to convert human-entered
|
|
text to terms. Program-generated values, like dates, keywords, etc.,
|
|
should be consistently program-generated.</li>
|
|
|
|
<li>In a query form, fields which are general text should use the query
|
|
parser. All others, such as date ranges, keywords, etc. are better added
|
|
directly through the query API. A field with a limit set of values,
|
|
that can be specified with a pull-down menu should not be added to a
|
|
query string which is subsequently parsed, but rather added as a
|
|
TermQuery clause.</li>
|
|
</ol>

|

<blockquote>
|
|
<p>A query is broken up into terms and operators. There are two types of terms: Single Terms and Phrases.</p>
|
|
<p>A Single Term is a single word such as "test" or "hello".</p>
|
|
<p>A Phrase is a group of words surrounded by double quotes such as "hello dolly".</p>
|
|
<p>Multiple terms can be combined together with Boolean operators to form a more complex query (see below).</p>
|
|
<p>Note: The analyzer used to create the index will be used on the terms and phrases in the query string.
|
|
So it is important to choose an analyzer that will not interfere with the terms used in the query string.</p>
