Choose indexing options, configure the "noise" or "stop" word list, and the list of file extensions excluded from indexing select Tools - Indexing.
Check the Rebuild index check box to completely rebuild the indexes in your matter. Re-indexing the matter without Rebuild index checked will examine all documents in the index but will only index new or modified documents.
The Noise Words list is used to exclude certain common words from being indexed. Excluding certain very common words has the benefit of increasing keyword search performance as well as the amount of disk space required to store the keyword indexes.
Select the Noise Words tab.
Add words to the list by typing the word into the row at the top of the word list next to the * symbol.
Remove noise words by selecting the words to remove and selecting the Delete key on the keyboard.
To restore the noise word list to the default list, click the Restore Defaults button.
Import an existing list of noise words from a text file using the Import… button.
Export the noise word list to a text file using the Export… button.

Note: Altering the noise word list requires that existing indexes be re-generated before the changes will take effect (Rebuild Indexes).
Select the Excluded Extensions tab to manage the extensions to be excluded from indexing.
Add extensions to the list by typing into the box at the top of the list next to the * symbol.
Remove extensions by selecting the rows to remove and hitting the Delete key on the keyboard.
To restore the excluded extension list to the default list of extensions, click the Restore Defaults button.
Import an existing list of extensions from a text file using the Import… button.
Export the extension list to a text file using the Export… button.
