Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Words and Phrases
| Search for | Example | Results |
|---|---|---|
| A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
|
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Using Boolean Operators
| Search for | Operator | Example |
|---|---|---|
|
Two or more words in the same topic |
|
|
| Either word in a topic |
|
|
| Topics that do not contain a specific word or phrase |
|
|
| Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
| A combination of search types | ( ) parentheses |
|
Stop word file
The stop word file, [ir_languagefiles_path]<language>.stp, contains a list of words used too frequently to index because that would hinder the identification of documents. Edit this list as you would a text file. Type each word on a separate line.
The words in the file go through a stemming process, which eliminates the need to specify all the forms for the word. For example, in English, you do not have to enter both "go" and "going" into the stop words file because the stemming algorithm changes "going" to "go." The only word that must be entered in the .STP file is the word "go."
