Full-Text Searches

 

 Using a full-text search, you can locate any word or phrase in a file stored as an electronic document (E-Document) in the STAR database. (Depending on your installation, the search may also include the Description and Synopsis fields of filings.) To get the specific results you’re looking for, however, you should become acquainted with a few basic rules and guidelines.

 

 This document provides the following information:

Basic Full-Text Search Rules

Rule

Search Criteria Entered

Results

Queries can include a single word.

Note: If you type more than one word, the system will automatically enclose them within quotation marks (see the following rule). Boolean or proximity operator will not be included within quotations.

pipeline

Files containing the word pipeline

Multiple words are automatically enclosed within quotation marks and are treated as a phrase. They must appear in the same order within a matching file. Do not enclose search in quotation marks.

Note: If you type more than one word, the system will automatically enclose them within quotation marks. Boolean or proximity operator will not be included within quotations.

pipeline regulations

Files containing the phrase pipeline regulations

Queries are not case sensitive; the search ignores capitalization.

RAM

Files containing the word RAM or ram

Common words — a, an, and, for, or, and the — are ignored during a search. Such words are treated as placeholders in the phrase.

Note: “AND” and “OR” also function as Boolean operators.

Word for Windows

Files containing a three-word phrase where the first word is “Word” and the third word is “Windows,” including Word for Windows and Word and Windows

Punctuation marks (for example, period [.], colon [:], semicolon [;], and comma [,]) are ignored during a search.

regulations: pipeline

Files containing the phrase regulations pipeline

 

 

Boolean and Proximity Operators

Boolean and proximity operators (AND, OR, NOT, and NEAR) can be used to produce more precise search results. Each operator has both a keyword and a symbol (or combination of symbols) that can be used in the search. Note: To use an operator as a word and not an operator, place quotation marks ( " ) around the phrase. For example, the search phrase “Abbott and Costello” returns files containing the three-word phrase where “Abbott” is the first word and “Costello” is the third words, such as Abbott and Costello, Abbott sees Costello, and Abbott baffles Costello.

 

Operator

Notes

Search Criteria Entered

Results

Keyword: AND Symbol: & Searches for: Files containing both terms

AND has a higher precedence in searches than OR. Refer to Precedence of Boolean Operators.

access AND basic access & basic

Files with both the words access and basic

Keyword: OR Symbol: | Searches for: Files containing either term

OR has a lower precedence in searches than AND. Refer to Precedence of Boolean Operators.

cgi OR isapi cgi | isapi

Files with the word cgi or isapi

Keyword: AND NOT Symbol: & ! Searches for: Files containing the first term without the second term

NOT may be used only in conjunction with AND, not alone (that is, AND NOT). When AND NOT is used, the search finds all matches for the first term and then excludes all matches that also include the second term.

access AND NOT basic access & ! basic

Files with the word access but not the word basic

Keyword: NEAR Symbol: ~ Searches for: Files containing both terms, located close together

NEAR functions similarly to AND—in other words, the matches returned contain both terms. However, the rank of the match indicates the closeness of the words to each other—the closer together the words are, the higher the rank. If they are more than 50 words apart, the result is assigned a rank of 0.

excel NEAR project excel ~ project

Files with the word excel near the word project

 

Precedence of Boolean Operators

In general, the search term is considered from the left to the right; however, this order is overridden in the following cases:

·         Anything in parentheses is considered first; therefore, use parentheses to nest expressions within a search.

·         AND takes precedence over OR (that is, AND operators are considered before OR operators).

 

 

Search Criteria Entered

Results

Pipeline AND regulations AND application AND tariff

Files containing all of the following terms:  Pipeline, regulations, application, and tariff

 

Pipeline AND regulations AND application OR tariff Tariff OR pipeline AND regulations AND application

Files containing all of the following terms:  Pipeline, regulations, application

 

And files containing the following single term:  Tariff

 

Pipeline AND regulations AND (application OR tariff) Pipeline AND (application OR tariff) AND regulations (Application OR tariff) AND pipeline AND regulations

Files containing all of the following terms:  Pipeline, regulations, application

 

And files containing all of the following terms:  Pipeline, regulations, tariff

 

 

 

 

 

Wildcards

At times, you may want to include variations of a word in your search results (for example, regulation as well as regulations, or regulation and regulations as well as regulatory). To do so, use a “wildcard,” which is indicated by an asterisk (*).

Important: Any search term with a wildcard must be enclosed within quotation marks (for example, “regulat*”); if the term is not enclosed within quotation marks, the * will not be treated as a wildcard. To use a wildcard, enter the characters that must match at the beginning of the word and then place the wildcard character (*) where there is a variation. Note: Wildcards can be used only at the end of a word—they cannot be used at the beginning of or in the middle of a set of characters (for example, “*ation” or “reg*s”).

 

Search Criteria Entered

Results

reg*

Files containing any word that begins with the letters “reg”, such as regency, regulation, regulations, regulator, regulators, and regulatory

regulat*

Files containing any word that begins with the letters “regulat”, such as regulation, regulations, regulator, regulators, and regulatory

regulati*

Files containing any word that begins with the letters “regulati”, such as regulation and regulations

regulato*

Files containing any word that begins with the letters “regulato”, such as regulator, regulators, and regulatory

 

 

Word Stems

Sometimes, variations of a word (especially verbs) are spelled dramatically different. For example, if you wanted all variations of the word “fly,” you would need a search for fly, flies, flying, flew, and flown. Because the words are so different, the only wildcard search that would find all of them would be “fl*”, but that would also match any other word that started with “fl”, such as flag and fluoride. However, because these words are all based on the same word stem (fly), you can use word stems to find all variations. To use word stems, use the search criteria formsof(inflectional, “[your search term]”) where [your search term] is replaced with the word stem for which you are searching.

 

Search Criteria Entered

Results

Formsof(inflectional, "fly")

Files with words based on the same stem as “fly”: fly, flies, flying, flew, and flown.

Formsof(inflectional, "eat")

Files with the words based on the same stem as “eat”: eat, eats, eating, ate, eaten.
