Wildcard Searches  

The 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  

The 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 specify 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  

The 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 "Metadot" and "help" within 10 words of each other in a document use the search:

"Metadot help"~10

Boosting a Term  

The 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

Metadot help

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

Metadot^4 help

This will make documents with the term Metadot appear more relevant. You can also boost Phrase Terms as in the example:

"Metadot help"^4 "Portal Server"

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. The 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 "Metadot help" or just "Metadot" use the query:

"Metadot help" Metadot

or

"Metadot help" OR Metadot

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 "Metadot help" and "Portal Server" use the query:

"Metadot help" AND "Portal Server"

+  

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 "Metadot" and may contain "help" use the query:

+Metadot help

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 "Metadot help" but not "Portal Server" use the query:

"Metadot help" NOT "Portal Server"

Note: The NOT operator cannot be used with just one term. For example, the following search will return no results:

NOT "Metadot help"

-  

The "-" or prohibit operator excludes documents that contain the term after the "-" symbol.

To search for documents that contain "Metadot help" but not "Portal Server" use the query:

"Metadot help" -"Portal Server"

Grouping  

The 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 "Metadot" or "help" and "website" use the query:

(metadot OR help) AND website

This eliminates any confusion and makes sure you that website must exist and either term Metadot or help may exist.
