Lucene supports AND, "+", OR, NOT and " -" as Boolean operators(Note: Boolean operators must be ALL CAPS).48 +Boolean operators allow terms to be combined through logic operators. Lucene supports AND, "+", OR, NOT and "-" as Boolean operators(Note: Boolean operators must be ALL CAPS). 60 60 61 61 The OR operator is the default conjunction operator. This means that if there is no Boolean operator between two terms, the OR operator is used. The OR operator links two terms and finds a matching document if either of the terms exist in a document. This is equivalent to a union using sets. The symbol || can be used in place of the word OR. 62 62 63 63 To search for documents that contain either "jakarta apache" or just "jakarta" use the query: 64 64 65 -{ {code}}54 +{code} 66 66 "jakarta apache" jakarta 67 -{ {/code}}56 +{code} 68 68 69 69 or 70 70 71 -{ {code}}60 +{code} 72 72 "jakarta apache" OR jakarta 73 -{ {/code}}62 +{code} 74 74 75 - ===AND===64 +1.1.1 AND 76 76 77 77 The AND operator matches documents where both terms exist anywhere in the text of a single document. This is equivalent to an intersection using sets. The symbol && can be used in place of the word AND. 78 78 79 79 To search for documents that contain "jakarta apache" and "Apache Lucene" use the query: 80 80 81 -{ {code}}70 +{code} 82 82 "jakarta apache" AND "Apache Lucene" 83 -{ {/code}}72 +{code} 84 84 85 - ===+===74 +1.1.1 + 86 86 87 87 The "+" or required operator requires that the term after the "+" symbol exist somewhere in a the field of a single document. 88 88 89 89 To search for documents that must contain "jakarta" and may contain "lucene" use the query: 90 90 91 -{ {code}}80 +{code} 92 92 +jakarta lucene 93 -{ {/code}}82 +{code} 94 94 95 - ===NOT===84 +1.1.1 NOT 96 96 97 97 The NOT operator excludes documents that contain the term after NOT. This is equivalent to a difference using sets. The symbol ! can be used in place of the word NOT. 98 98 99 99 To search for documents that contain "jakarta apache" but not "Apache Lucene" use the query: 100 100 101 -{ {code}}90 +{code} 102 102 "jakarta apache" NOT "Apache Lucene" 103 -{ {/code}}92 +{code} 104 104 105 105 Note: The NOT operator cannot be used with just one term. For example, the following search will return no results: 106 106 107 -{ {code}}96 +{code} 108 108 NOT "jakarta apache" 109 -{ {/code}}98 +{code} 110 110 111 - ===- ===100 +1.1.1 - 112 112 113 -The " -" or prohibit operator excludes documents that contain the term after the "-" symbol.102 +The "-" or prohibit operator excludes documents that contain the term after the "-" symbol. 114 114 115 115 To search for documents that contain "jakarta apache" but not "Apache Lucene" use the query: 116 116 117 -{ {code}}106 +{code} 118 118 "jakarta apache" -"Apache Lucene" 119 -{ {/code}}108 +{code} 120 120 121 - ===Grouping===110 +1.1.1 Grouping 122 122 123 123 Lucene supports using parentheses to group clauses to form sub queries. This can be very useful if you want to control the boolean logic for a query. 124 124 125 125 To search for either "jakarta" or "apache" and "website" use the query: 126 126 127 -{ {code}}116 +{code} 128 128 (jakarta OR apache) AND website 129 -{ {/code}}118 +{code} 130 130 131 131 This eliminates any confusion and makes sure you that website must exist and either term jakarta or apache may exist. 132 132 133 - ===Field Grouping===122 +1.1.1 Field Grouping 134 134 135 135 Lucene supports using parentheses to group multiple clauses to a single field. 136 136 137 137 To search for a title that contains both the word "return" and the phrase "pink panther" use the query: 138 138 139 -{ {code}}128 +{code} 140 140 title:(+return +"pink panther") 141 -{ {/code}}130 +{code} 142 142 143 - ==Escaping Special Characters==132 +1.1 Escaping Special Characters 144 144 145 145 Lucene supports escaping special characters that are part of the query syntax.

( ) { } [ ] ^ " ~ * ? : \ 149 -{ {/code}}138 +{code} 150 150 151 -To escape these character use the before the character.
