# QuerySummaryStopPhraseMode

The QuerySummary stop phrase mode to use. Stop phrases allow you to filter the list of phrases that IDOL Server produces when you use the QuerySummary action parameter.

Set this parameter to one of the following values, or a sum of values:

`1` | Enable `QuerySummary` stop phrases.
`2` | Use database restrictions when automatically generating new QuerySummary stop phrases. In this mode, IDOL Server generates the stop phrases based on a selection of documents for each database (by default it uses a random sample of all documents). All stop phrases apply to all queries and all databases.
`4` | Generate new QuerySummary stop phrases at startup if none exist.
`8` | Generate additional QuerySummary stop phrases at startup, appending to existing values.
`16` | Remove existing stop phrases before generating new ones.
`32` | Use case-insensitive phrase matching.

When you enable stop phrases, IDOL Server stores them in the `qssp.db` file in the Content component root directory. HPE recommends that you use `QuerySummaryStopPhraseMode` `4` or `8` to automatically create this list. With mode `8`, IDOL Server automatically detects very common phrases in IDOL Server when you start it, and adds them to the list. This list might include common boilerplate text, such as a disclaimer or e-mail signature.

You can modify the file manually to add any other stop phrases that you do not want to appear in your query summary lists. The stop phrase file must contain one percent-encoded phrase on each line. For example:

    phrase%20one
    phrase%20two

By default, IDOL Server considers all phrases in their entirety. For example, if you specify `Company` as a list item, it affects only query summary results where `Company` is the whole query summary phrase, and not all query summary phrases that contain `Company`.

To remove any query summary phrase that contains a specified subphrase, prefix the subphrase with an asterisk (*). For example, if you specify `*Company` as a list item, it affects any query summary result phrase that contains the subphrase `Company`, such as Company News, or Top Headlines for Company.
