    Wildcard Searches

    YoGet search engine supports single and multiple character wildcard searches within single terms (not within phrase queries).

    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 that 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
    Note: You cannot use a * or ? symbol as the first character of a search.

    Fuzzy Searches

    YoGet search engine supports fuzzy searches based on the Levenshtein Distance, or Edit Distance algorithm. To do 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. An additional (optional) parameter can be specified the required similarity. The value is between 0 and 1, with a value closer to 1 only terms with a higher similarity will be matched. For example:
    roam~0.8
    The default that is used if the parameter is not given is 0.5.

    Proximity Searches

    YoGet search engine supports finding words are a within a specific distance away. To do a proximity search use the tilde, "~", symbol at the end of a Phrase. For example to search for a "yoget" and "news" within 10 words of each other in a document use the search: 
    "yoget news"~10
    Boosting a Term

    YoGet search engine provides the relevance level of matching documents based on the terms found. To boost a term use the caret, "^", symbol with a boost factor (a number) at the end of the term you are searching. The higher the boost factor, the more relevant the term will be.

    Boosting allows you to control the relevance of a document by boosting its term. For example, if you are searching for
    yoget news

    and you want the term "yoget" to be more relevant boost it using the ^ symbol along with the boost factor next to the term. You would type:
    yoget^4 news

    This will make documents with the term "yoget" appear more relevant. You can also boost Phrase Terms as in the example: 
    "yoget news"^4 "online forum"

    By default, the boost factor is 1. Although the boost factor must be positive, it can be less than 1 (e.g. 0.2)


    Boolean Operators

    Boolean operators allow terms to be combined through logic operators. YoGet search engine supports AND, "+", OR, NOT and "-" as Boolean operators(Note: Boolean operators must be ALL CAPS).

    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.

    To search for documents that contain either "yoget news" or just "yoget" use the query:
    "yoget news" yoget

    or
    "yoget news" OR yoget

    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 "yoget news" and "social networks" use the query: 
    "yoget news" AND "social networks"
    +
    The "+" or required operator requires that the term after the "+" symbol exist somewhere in a the field of a single document.

    To search for documents that must contain "yoget" and may contain "news" use the query:
    +yoget news

    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 "yoget news" but not "social networks" use the query: 
    "yoget news" NOT "social networks"

    Note: The NOT operator cannot be used with just one term. For example, the following search will return no results:
    NOT "social networks"
    -
    The "-" or prohibit operator excludes documents that contain the term after the "-" symbol.

    To search for documents that contain "yoget news" but not "social networks" use the query: 
    "yoget news" -"social networks"


    Grouping

    YoGet search engine 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.

    To search for either "yoget" or "news" and "forum" use the query:
    (yoget OR news) AND forum

    This eliminates any confusion and makes sure you that "forum" must exist and either term "yoget" or "news" may exist.
