# Customize Agent Content

In large systems that experience heavy load, you can optimize the performance of AgentBoolean queries by creating optimized agents or categories. This optimization is most useful when you use Knowledge Discovery to:

- Return agents that match a non-indexed document, for example to alert users to new content that matches their agents.

- Return categories that match a non-indexed document, for example to categorize a document and add the category information to a field before indexing.

When Agentstore matches query text against agents or categories, it uses the following matching order:

1. It matches the query text against the `Index` fields in the agents or categories (for example the `TRAINING` or `DRECONTENT` fields).

2. For agents that match in Step 1, it matches the query text against any Boolean restrictions in the agents or categories.

3. For agents that match in Step 2, it matches the query text against any `FieldText` restrictions in the agents or categories.

Agentstore checks the Boolean restriction only if the agent or category content matches the document.

To optimize performance, choose your category or agent content carefully to ensure that it matches only query text that is also likely to match the Boolean expression.

## Use a Minimal List of Rare Terms

For many Boolean restrictions, you can select one or two terms that queries must contain to match the Boolean expression. If you select the rarest of these combinations, fewer documents match the agent content. This process reduces the number of Boolean expressions that Agentstore must match.

For example, if your Boolean restriction is:

    “New Zealand” AND “French Champagne”

you can set the agent content to:

    Zealand

In this Boolean expression, the query text must contain all four terms, so you can choose any of them as the agent content. `Zealand` is the rarest term, so fewer documents match this agent.

For other expressions, you can often similarly choose a minimal list of terms to reduce the number of documents that match against the Boolean restriction.

To find the minimal list of terms

- Send the `DocumentStats` action with the `QueryStats` parameter set to `True`. For example:

      http://localhost:9050/action=DocumentStats&Text=“New Zealand” AND “French Champagne”&QueryStats=True

This action returns a minimal list of terms that text must contain to match the Boolean expression. It provides the rarest terms where possible. The action returns the following information:

    <autnresponse>
       <action>DOCUMENTSTATS</action>
       <response>SUCCESS</response>
       <responsedata>
          <autn:wildrequired>false</autn:wildrequired>
          <autn:numberrequired>1</autn:numberrequired>
          <autn:required>ZEALAND</autn:required>
       </responsedata>
    </autnresponse>

Using this method to choose the agent or category content can improve performance, especially in systems that receive a large number of queries.

## Use AlwaysMatchType Fields

For some Boolean expressions that include Wildcards and `DREFUZZY` or `SOUNDEX` expressions, the minimal list of terms must include a Wildcard value.

For these expressions, the `DocumentStats` action with the `QueryStats` set to `True` returns the following line:

    <autn:wildrequired>true</autn:wildrequired>

The agent or category content cannot contain a Wildcard value, so you must use a different approach to ensure that Agentstore checks the Boolean expression.

You can ensure that Agentstore checks any documents that contain one of these expressions by configuring an `AlwaysMatchType` field in the Agentstore component and adding it to the agents.

Agentstore always matches the content of an agent or a category that contains an `AlwaysMatchType` field. It then attempts to match the query text against the Boolean restriction, and returns any agents or categories that match at this stage.

To configure AlwaysMatchType fields

1. Open the IDX or XML files that contain your AgentBoolean documents.

2. Decide which fields you want to always match. For a document to always match, the `AlwaysMatchType` field must have a non-empty string.

   NOTE: For categories, you must use the `NOCONTENTCAT` field.

3. Open the Agentstore component configuration file in a text editor.

4. In the `[FieldProcessing]` section, add a new process to the list of processes. This process identifies the fields in the IDX or XML document that you want to always match. For example:

       [FieldProcessing]
       0=SetIndexFields
       ...
       15=SetAlwaysMatchFields

5. Create a new section for the process that you added. In this section, create a property for the process (you define the property, later by setting one or more applicable configuration parameters). Set `PropertyFieldCSVs` to a list of fields to associate with the process. For example:

       [SetAgentBooleanFields]
       Property=AlwaysMatchFields
       PropertyFieldCSVs=*/MARKERFIELD,*/NOCONTENTCAT

6. Create a new section for the property that you added, in which you set `AlwaysMatchType` to `True`. This property indicates that Agentstore must always match the associated fields in queries. For example:

       [AlwaysMatchFields]
       AlwaysMatchType=True

7. Save and close the configuration file.

8. Restart the Agentstore component for your changes to take effect.

After you configure the `AlwaysMatchType` field, you must manually create agents as IDX or XML documents.

For each agent, send the Boolean restriction in a `DocumentStats` action to the Content component to return the minimal list of terms.

- If the result does not contain a Wildcard value, you can create agents in the normal way.

- If the result contains a Wildcard, add the `AlwaysMatchType` field to the agent IDX. For example:

    #DREREFERENCE WineAgent
    #DRETITLE My Wine Agent
    #DREFIELD BOOLEANRESTRICTION=""Champ*" AND "Merlot""
    #DREFIELD MARKERFIELD="1"
    #DRECONTENT
    #DREENDDOC

You can index your agent IDX or XML document into the Agentstore component agent database by using a `DREADD` or `DREADDDATA` index action. For example:

    http://localhost:9051/DREADD?C:\data\Agents.idx&DREDBName=Agent

NOTE: OpenText recommends that you do not use `AlwaysMatchType` fields without also specifying either the Boolean or FieldText restriction. If you add an `AlwaysMatchType` field to the agent or category without any other restriction, it returns for every query.

If you do have agents or categories of this kind, you can use `FieldText` in your agent or category query to filter them out. For example:

    FieldText=EXISTS{}:BOOLEANRESTRICTION OR EXISTS{}:FIELDTEXTRESTRICTION

This example restricts the results of the query to agents and categories that have one of the restriction fields.
