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.

Search for	Operator	Example
Two or more words in the same topic	`AND` `and` `+` (plus symbol) `&` (ampersand)	`cat AND dog` `"cat food"+milk` `"cat food"&"dog food"`
Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`
Topics that contain one string and do not contain another	`^` (caret)	`cat ^ mouse`

Scan File Processing Power

When the scan files flow into the incoming directory of the XML Enricher faster than the XML Enricher is able to process them, a build-up of scan files occurs in the incoming directory. To allocate more processing power for enriching scan files, Universal Discovery can be configured to allocate more resources to accommodate this load.

Configuring Threads

In general, higher numbers of threads that are allocated to the XML Enricher service results in higher amounts of CPU and memory that the XML Enricher process consumes. As a result, the processing of scan files runs faster and faster. However, too many threads may slow down the processing if there is not enough CPU or memory resources available. In this case, disk performance becomes a constraining factor.

It is recommended to experiment with this setting using gradual changes and then analyze the results in the incoming directory of the XML Enricher.

To configure the maximum number of processing threads in the XML Enricher service, see How to Configure the Maximum Number of Threads to Process Scan Files.

Configuring Memory Mode or Database Mode

You can configure the mode in which the XML Enricher service runs when processing scan files. Select the mode that best suits your system or business needs as follows.

Mode	Memory Usage	Hard Disk Usage
Memory	High	Low
Database	Low	High

To configure this mode, see How to Configure XML Enricher to Suit the Probe Deployment Mode.
