Basic SearchesTo do a basic search, enter some search terms. For example: This will search for documents containing the words white, puppy or adoption
GroupingYou can group search terms using parantheses to form sub queries. For example, to find results about different colors of dogs, try the following For more explanation on the OR and AND operators see below in the "Boolean operators" section
Wildcard SearchesWildcard searches let you look for parts of words. The single character wildcard search (?) looks for terms that match that with the single character replaced. For example, to search for "text" or "test" you can use the search: Multiple character wildcard searches (*) looks for 0 or more characters. For example, to search for test, tests or tester, you can use the search: You can also use the wildcard searches in the middle of a term.
Fuzzy SearchesFuzzy searches return results that match your search terms exactly as well as results that are close. For example, if you want to find a word that is similar to foam add a tilde (~) to your search term: This search will match terms like foam and roams.
Proximity SearchesProximity searches help you find words that are close to each other. For example, if you know the word "Bill" and "Monica" are within 5 words of each other you can write your query like this:
Boosting a TermBoosting a search term gives it more weight in the result list. For example, if you search for "black cat" you might get results about black paint and cats but not necessarily black cats. In this case, we want to tell the search engine to weight the word "cat" more heavily: You can also boost phrases: You can use any number to boost the term -- the higher the number the higher the boosting. For example, if the query above still returns too many results, consider increasing the boost value:
Boolean operatorsBoolean operators allow terms to be combined for more advanced searches. The terms AND, OR, NOT, + (plus sign) and -(minus sign) are supported. Note, these terms must be in ALL CAPS to distinguish them from normal words.
ORThe OR operator links two terms and finds a matching document if either of the terms exist in a document. Note, the symbol || can be used in place or the word OR. To search for documents that contain either "black cat" or just "cat adoption" use the query: or Note: OR is the default search term, so the following search is equivalent to both of the previous examples:
ANDThe AND operator matches documents where both terms in the text of the document. The symbol && can be used in place of the word AND. This is a more restrictive search than an OR search. To search for documents that contain "black cat" and "cat adoption" use the query: or
NOTThe NOT operator excludes documents that contain terms after NOT. The ! symbol can be used in place of the word NOT. To search for documents that contain "black cat" but not "cat adoption" use the query: or Note: The NOT operator must be used with multiple terms. For example, the following search will return no results:
The "+" SignThe + operator tells the search engine that the search term must appear in a document to be a match. To search for documents that must contain "black cat" and may contain "cat adoption" use the query:
The "-" SignThe - operator excludes documents that contain the term after the "-" symbol. To search for documents that contain "black cat" but not "cat adoption" use the query:
Escape CharactersThere are a number of special characters that are part of the query syntax. The current list special characters are: To escape these character use the \ before the character. For example to search for (1+1):2 use the query:
