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.
|A single word||
||Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".|
You can specify that the search results contain a specific phrase.
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.
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||
|A combination of search types||

Updates to IR files
You can update IR files in two modes:
The default mode.
The system places changes to the IR key in a queue. They are not processed immediately. A separate background process (IRQUEUE), writes the accumulated updates into the IR index files. The changes are then available for searches. Query response time is faster when using Asynchronous IR. In asynchronous mode, updates to files that have an IR key do not have to wait for the completion of IR queries that are executing at the same time.
Note If the IRQUEUE process is not running for any reason, changes to IR index data are not available to users. IR files do not reflect the newest IR index data and therefore will not retrieve newly added data. However, searches will work against existing IR data.
The system immediately writes All IR Expert updates into the IR Expert files. The IRQUEUE processor is not used.
