Often, just typing a few keystrokes is not enough to find the documents you want. LGEAN provides a wealth of search operators to help you get the job done. By including special words like AND, OR, and NOT in your search criteria, or by using various wildcards (Dfn. WILDCARD - From card games in which certain cards, often the joker, can act as
any other card. A special character or character sequence which matches any character in a string comparison, like ellipsis ("...") in ordinary written text.), you can tweak your search to find exactly what you're looking for.
A Note Regarding Case Sensitivity
A search becomes case sensitive whenever the characters provided are of mixed case.
Search using either storm or STORM will find results for: storm, Storm, or STORM.
However, a search for Storm will only find results only for Storm.
Using AND, OR, and NOT
If you want to refine your search a little, you can use special search operators in your search criteria to get more specific. Only the most common search operators are discussed at this point. There are many others available for your use under ADVANCED HELP.
The table below briefly describes the effect of using AND, OR, and NOT in your search criteria.
Basic Search Operators
Operator |
Effect |
Example |
AND |
Searches for documents that have both words in it. |
Storm and Water |
OR |
Searches for documents that has either word in it. |
Storm or Water |
NOT |
Eliminates documents where the word following NOT is found. |
Storm not Water |
A comma can be used instead of OR in search criteria. A search for Storm, Water is therefore the same as a search for Storm or Water.
Simple Queries and Wildcards
Simple queries allow users to enter simple, comma-separated terms and statements with and use wildcard characters. By default, a simple query searchs for words. For example, entering the word "ALL" will find documents containing the word "all" but not "allegorical." You can use wildcards, however to broaden the scope of the search. "ALL*" will return documents containing both "all" and "alliterate." Case is ignored.
Search for ALL will return only documents with "ALL."
Search for ALL* will return documents with "ALL" and "ALLiterate."
You can enter multiple words separated by commas: storm, water, regulations. The comma in a simple query expression is treated like a logical OR. If you omit the commas, the query expression is treated as a phrase, so documents would be searched for the phrase "storm water regulations."
Search for storm , water will return documents with
STORM or WATER
Search for storm water will return documents with
STORM WATER
Ordinarily, operators are employed in explicit query expressions. Operators are normally surrounded by angle brackets < >. However, you can use the AND, OR, and NOT operators in a simple query without using angle brackets: storm AND (water OR regulations). To include an operator in a search, you surround it with double quotation marks: storm "and" water. This expression searches for the phrase "storm and water".
Search for storm AND (water OR regulations) will return documents with
STORM WATER & STORM REGULATIONS
Search for storm "AND" water will return documents with
STORM AND WATER
