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 |

Key types
Fields that define the key fields in the Database Dictionary (Dbdict) of a file. These key fields create the indexes used in queries to make searching for records fast and efficient.
Key types allow or disallow certain values across all records within the file for the combined fields that comprise the key, and assist in maintaining data integrity by controlling the field values in a key. The key types include unique, no nulls, no duplicates, and nulls & duplicates. IR Expert uses separate keys.
