-<p>This DTD builds on the <a href="LuceneCoreQuery.dtd.html">core Lucene XML syntax</a> and adds support for features found in the "contrib" section of the Lucene project.</p><p>CorePlusExtensionsParser.java is the Java class that encapsulates this parser behaviour.</p><p>The features added are:
-<ul>
-<li><a href="#LikeThisQuery">LikeThisQuery</a></li>
-Support for querying using large amounts of example text indicative of the users' general area of interest
-<li><a href="#FuzzyLikeThisQuery">FuzzyLikeThisQuery</a></li>
-A style of fuzzy query which automatically looks for fuzzy variations on only the "interesting" terms
-<li><a href="#BooleanFilter">BooleanFilter</a></li>
-Is to Filters what core Lucene's BooleanQuery is to Queries - allows mixing of clauses using Boolean logic
-<li><a href="#TermsFilter">TermsFilter</a></li>
-Constructs a filter from an arbitrary set of terms (unlike <a href="#RangeFilter">RangeFilter</a> which requires a contiguous range of terms)
-<li><a href="#DuplicateFilter">DuplicateFilter</a></li>
-Removes duplicated documents from results where "duplicate" means documents share a value for a particular field (e.g. a primary key)
-<li><a href="#BoostingQuery">BoostingQuery</a></li>
-Influence score of a query's matches in a subtle way which can't be achieved using BooleanQuery

- IRAQI TROOPS REPORTED PUSHING BACK IRANIANS Iraq said today its troops were pushing Iranian forces out of

- Basra early yesterday. A High Command communique said Iraqi troops had won a significant victory
- and were continuing to advance. Iraq said it had foiled a three-pronged thrust some 10 km
- (six miles) from Basra, but admitted the Iranians had occupied ground held by the Mohammed al-Qassem
- unit, one of three divisions attacked. The communique said Iranian Revolutionary Guards were under
- assault from warplanes, helicopter gunships, heavy artillery and tanks. "Our forces are continuing
- their advance until they purge the last foothold" occupied by the Iranians, it said.
- (Iran said its troops had killed or wounded more than 4,000 Iraqis and were stabilising their new positions.)
- The Baghdad communique said Iraqi planes also destroyed oil installations at Iran's southwestern Ahvaz field
- during a raid today. It denied an Iranian report that an Iraqi jet was shot down.
- Iraq also reported a naval battle at the northern tip of the Gulf. Iraqi naval units and forces defending an
- offshore terminal sank six Iranian out of 28 Iranian boats attempting to attack an offshore terminal,
- the communique said. Reuters 3;

+<p>This DTD builds on the <a href="LuceneCoreQuery.dtd.html">core Lucene XML syntax</a> and adds support for features found in the "contrib" section of the Lucene project.</p><p>CorePlusExtensionsParser.java is the Java class that encapsulates this parser behaviour.</p><p>The features added are:
+<ul>
+<li><a href="#LikeThisQuery">LikeThisQuery</a></li>
+Support for querying using large amounts of example text indicative of the users' general area of interest
+<li><a href="#FuzzyLikeThisQuery">FuzzyLikeThisQuery</a></li>
+A style of fuzzy query which automatically looks for fuzzy variations on only the "interesting" terms
+<li><a href="#BooleanFilter">BooleanFilter</a></li>
+Is to Filters what core Lucene's BooleanQuery is to Queries - allows mixing of clauses using Boolean logic
+<li><a href="#TermsFilter">TermsFilter</a></li>
+Constructs a filter from an arbitrary set of terms (unlike <a href="#RangeFilter">RangeFilter</a> which requires a contiguous range of terms)
+<li><a href="#DuplicateFilter">DuplicateFilter</a></li>
+Removes duplicated documents from results where "duplicate" means documents share a value for a particular field (e.g. a primary key)
+<li><a href="#BoostingQuery">BoostingQuery</a></li>
+Influence score of a query's matches in a subtle way which can't be achieved using BooleanQuery
