![]() Prints a user-readable version of this query. Specifies a minimum number of the optional BooleanClauses which must be satisfied. Void setMinimumNumberShouldMatch(int min) Sets the maximum number of clauses permitted per BooleanQuery. Static void setMaxClauseCount(int maxClauseCount) Returns an iterator on the clauses in this query.Įxpert: Called to re-write queries into primitive queries. Returns true if ord(int,int) is disabled in scoring for this query instance. To rewrite to a simpler form, instead return a simpler enum from getTermsEnum(Terms, AttributeSource). Returns a hash code value for this object. Gets the minimum number of the optional BooleanClauses which must be satisfied. Returns the maximum number of clauses permitted, 1024 by default. Returns the set of clauses in this query. ![]() Returns true if object o is equal to this.Įxpert: Adds all terms occurring in this query to the terms set. Returns the list of clauses in this query.Įxpert: Constructs an appropriate Weight implementation for this query. Void add(Query query, BooleanClause.Occur occur) The following table shows the different class methods − S.No. The following table shows the different class constructors − S.No. Class Declarationįollowing is the declaration for the .BooleanQuery class −įollowing is the field for the BooleanQuery − BooleanQuery is used to search documents which are a result of multiple queries using AND, OR or NOT operators. GetIndex ( "sitecore_web_index" ) using ( var context = index. The following example shows how a typical Lucene query may be executed in Sitecore 7+ using LINQ. If the requirements for an upcoming project is similar to an existing benchmark, you will also have something to work with when designing the system architecture for the application. This makes it easy for us to swap the logic in the helper methods with the new Sitecore 7+ support. The purpose of these user-submitted performance figures is to give current and potential users of Lucene a sense of how well Lucene scales. The details of how the query was executed and how the results were returned was contained within the helper methods. In some cases we want to continue to use the string based queries so we don’t have to rework them into the new LINQ syntax, simply to save time.įor Sitecore 6.6, we abstracted the logic of executing the queries into helper methods. ![]() It is now time to upgrade those sites to newer versions of Sitecore to take advantage of the new features and improvements. We built several sites on Sitecore 6.6 using the string-based queries. A second way was to form a string-based representation of a query using the Lucene Query Parser to interpret the string. This provided an object model to create complex queries. ![]() The first way was to build up a query using the Field Query Object Model. Prior to Sitecore 7, developers generally had 2 ways to build the query. Developers can now use LINQ-based queries to retrieve data from the Lucene indexes. A Phrase is a group of words surrounded by double quotes such as 'welcome lucene '. A Single Term is a single word such as 'test' or 'sample'. ![]() Terms are of two types: 1.Single Terms and 2.Phrases. A query is broken up into terms and operators. Among those improvements was the added LINQ support for Lucene queries. The Apache Lucene project develops open-source search software. Lucene has a custom query syntax for querying its indexes. Sitecore 7 introduced many improvements to Lucene Search. ![]()
