FULL TEXT SEARCH
Because of the volume of documents that a Content Search must handle, some searches are faster than others. To determine the best search method for your particular task, consider these factors:
If you are performing a search for a word that contains a period at the end, such as Mr. or U.S.A., the search engine will assume that the final period is the end of a sentence and will not index it. Enter the words without the final period, as in Mr and U.S.A, to locate them.
Special characters, such as those used as wildcards and precedence expressions, are not indexed, so you cannot search for them. In such a case, you could simply enter your search without the characters. For a phone number, enter the number using spaces instead of parentheses or dashes, as in 781 555 3800.
A common problem is searching for a broad topic. If your Search Results list is too long for you to find the document for which you are looking, you should narrow your search. Include more operators or select Profile fields (Author, Entered by) for a more specific search. A search for a specific document containing the term Alimony is more easily found if you include other terms to narrow the search. For example, Alimony <AND> Caldwell <AND> December returns a more focused list than one of these search operators alone. The PHRASE and NEAR/n proximity operators are more useful in a case where a normal "AND" search might deliver a very large list.

Below are a few examples of search criteria that are acceptable in the Boolean Search field of the Content Search tab. The DM Webtop will convert the criteria and send a query to the DM Server.
For additional information on available search operators that can be used in content searching, see Search Operators.
hotel & reservation ◊ searches for: hotel AND reservation
hotel | reservation ◊ searches for: hotel OR reservation
hotel& ^ reservation ◊ searches for: hotel BUT NOT reservation
hotel%reservation ◊ searches for: hotel NEAR reservation
"hotel reservation" ◊searches for: PHRASE containing hotel and reservation
hotel|(reservation & deposit) ◊ searches for: hotel OR BOTH reservation AND deposit
Types of Syntax in Content Searching
Simple Syntax
When using simple syntax with the DM Server Indexer, relevance is strict Boolean with critical terms ordered. This means that terms that occur in fewer documents will have a higher priority, making documents containing these terms have a higher relevance. When documents are relevance-ranked, they are listed in an order based on their importance to your search criteria. Relevance-ranked results are presented with the most relevant documents at the top of the list.
Explicit Syntax
When you enclose individual words in double quotation marks, the Indexer interprets those words literally. For example, by entering the word "generator" in double quotation marks, the words "generate" and "generation" will not be considered in the search. To retrieve documents containing the word "generator" without searching for its stemmed variations, enter the word "generator" using explicit syntax:
"generator"
Precedence Expressions in Content Searching
The language used for composing search statements has a set of rules that determine the precedence for evaluation. An Indexer query expression is processed using explicit precedence rules applying to the operators used. While a query expression is read from left to right, some operators carry more weight than others and this will affect the interpretation of the expression. For example, an AND operator takes precedence over an OR operator.
Precedence Expression
Use
Parentheses ( )
Parentheses indicate the order the directions are to be carried out; information within parentheses is read first, then information outside parentheses is read next.
Prefix and Infix Notation
Words that use any operator, except the operators WILDCARD and WORD, can be defined in prefix notation or infix notation.
Prefix notation is a format specifying that the operator comes before the words to be used with that operator. When prefix notation is used, precedence is explicit within the expression.
Infix notation is a format specifying that the operator is to be specified between each element within the expression. When infix notation is used, precedence is implicit within the expression; for example, the AND operator takes precedence over the OR operator.
If you are using the DM Server Indexer, infix notation should not be combined with prefix notation in the same query.
Commas ,
If an expression includes two or more words within parentheses, as is used in prefix notation, a comma is required as a separator between each element enclosed within the parentheses.
Angle Brackets < >
Left and right angle brackets (< >) are reserved for designating operators and modifiers. They are not required.
Double Quotation Marks " "
To search for a word that is reserved as an operator ("and," "or," and "not"), enclose the word in double quotation marks.
Wildcards in Content Searching
The following wildcards can be used in content searching:
Wildcard
Definition
Example
?
Specifies one alphanumeric character.
?an locates ran, pan, can, and ban
*
Specifies one or more of any alphanumeric characters. You should not use * to specify the first character of a wildcard string.
corp* locates corporate, corporation, corporal, and corpulent.
Search Operators
Operators represent logic to be applied to a search element. This logic defines the qualifications a document must meet to be retrieved.
Operator
Description
WORD
Searches for a word.
AND
Searches for documents containing all of two or more search terms, and provides relevance-ranked results.
OR
Searches for documents containing one of two or more search terms, and provides relevance-ranked results.
NEAR/n
Searches for information containing two or more words within n number of words of each other, where n is an integer.
NOT
Searches for documents based on evidence not found in the documents.
PARAGRAPH
Selects documents that include all of the search elements you specify within the same paragraph.
PHRASE
Searches for information containing two or more words in the same phrase.
SENTENCE
Selects documents that include all of the search elements you specify within the same sentence.
THESAURUS
Expands the search to include the word you enter and its synonyms.
AND Operator
The And operator searches for documents that contain all of the search elements you specify. Documents retrieved using the AND operator are relevance-ranked.
To search for documents that contain the phrase "pharmaceutical companies" and the word "stock":
pharmaceutical companies AND stock
To search for documents that contain both the words "data" and "security":
data AND security
NEAR/n Operator
The NEAR/n operator is a proximity operator used to search for information containing two or more words within n number of words of each other, where n is an integer. The Indexer will assign document scores based on the relative distance of search terms, when the terms are separated by n words or less; words separated by more than n words will not be assigned scores and will not be retrieved. For example, if NEAR/5 is used to find two terms within five words of each other, a document that has the two terms within two words of each other scores higher than a document that has the two terms within five words of each other.
The N variable can be an integer between 1 and 1,024, where NEAR/ 1 searches for terms that are next to each other. If N is 1,000 or above, the N value must be given without a comma.
To search for relevance-ranked documents that contain search terms within N words of each other, the following syntax can be used.
Simple Syntax = wordA <NEAR/N> wordB <NEAR/N> wordC ...
Explicit Syntax = <NEAR/N> (wordA, wordB, wordC, ...)
To search for the term "air" within 10 words of the term "pollution," you can use one of the query expressions below.
Simple Syntax = air <NEAR/10> pollution
Explicit Syntax = <NEAR/10> (air, pollution)
Using the ORDER modifier with NEAR/N allows you to perform ordered searches. To search for the terms "air" and "pollution" within two words of each other, you can use one of the query expressions below.
Simple Syntax = air <ORDER> <NEAR/2> pollution
Explicit Syntax = <ORDER> <NEAR/2> (air, pollution)
NOT Operator
The NOT modifier searches for documents based on evidence not found in the documents. You can use the NOT modifier with a word or phrase to exclude documents that show evidence of that word or phrase. The NOT modifier can be used only with the operators AND and OR.
Simple Syntax
To find only documents that contain the words "cat" and "mouse" but not the word "dog," you can enter the following:
cat, mouse <AND> <NOT> dog
Explicit Syntax
You can ensure documents that contain words that have a different connotation from what you intend are not retrieved. For example, the word "coke" may ref.
