Wildcard Searches
SearchBlox supports single- and multiple-character wildcard searches. To perform a single character wildcard search, use the “?” symbol. To perform a multiple character wildcard search, use the “*” symbol.
The single character wildcard search looks for terms that match with the single character replaced. For example, to search for “text” or “test” you can use the search:
te?t
Multiple character wildcard searches looks for 0 or more characters. For example, to search for test, tests or tester, you can use the search:
test*
You can also use the wildcard searches in the middle of a term.
te*t
Fuzzy Searches
SearchBlox supports fuzzy searches. To perform a fuzzy search, use the tilde (~) symbol at the end of a single word term. For example, to search for a term similar in spelling to “roam”, use the fuzzy search:
roam~
This search will find terms like "foam" and "roams".
Proximity Searches
SearchBlox supports finding words that are a within a specific distance. To do a proximity search, use the tilde (~) symbol at the end of a phrase. For example, to search for “searchblox” and “j2ee” within 10 words of each other in a document use the search:
“searchblox j2ee”~10

Boolean Operators
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).
OR
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 union using sets. The symbol || can be used in place of the word OR. To search for documents that contain either “searchblox server” or just “searchblox” use the query:
“searchblox server” OR searchblox
Giving the following query yields the same as the one given above with OR operator:
searchblox j2ee
AND
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. To search for documents that contain “searchblox” and “j2ee” use the query:
searchblox AND j2ee
Plus Operator "+"
The “+” or required operator requires the term after the “+” symbol to exist somewhere in the field of a single document. To search for documents that must contain “searchblox” and may contain “j2ee” use the query:
+searchblox j2ee
NOT
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. To search for documents that contain “searchblox server” but not “j2ee” use the query:
“searchblox server” NOT j2ee
