Set up the Field Index Process

Topics in this Section

Autonomy connectors aggregate content and metadata, process it and then index it into IDOL server in the form of fields. To improve IDOL server performance, divide these fields into the following groups:
*
Prevent from storing. Prevent IDOL server from storing fields that you do not want to query by setting the CantHaveFieldsCSVs parameter in your IDOL server configuration file. Alternatively, add the CantHaveFields parameter to your DREADD or DREADDDATA indexing command.
*
Index fields. Store fields that contain text that you want to query frequently as Index fields. IDOL server processes Index fields linguistically when it stores them. IDOL server applies stemming and stop word lists to the text, which allows IDOL server to process queries for these fields more quickly. Typically, you set up DRETITLE and DRECONTENT as Index fields.
Do not use Index fields to store URLs or content that you are unlikely to use. Also, when you query the value only in its entirety, it is more efficient to query with a field specifier (for example, MATCH), than to store the data in an Index field.
Autonomy does not recommend indexing all fields in documents because it can potentially slow the indexing process, increase disk usage, and increase requirements.
*
Numeric fields. Store fields that contain numerical values or dates as numeric fields and numeric date fields. When IDOL server indexes these fields, it stores them in a fast look-up table in memory, which enables it to return the fields more quickly.
*
Field-check fields. If a large number of the documents you want to store in IDOL server contain a field whose entire value is frequently used to restrict results, store this field as a FieldCheckType field. When IDOL server indexes these fields, it stores them in a fast look-up table in memory, which enables it to return the field more quickly.
*
Ordinary fields. By default IDOL server stores all fields that are not identified as special fields as ordinary fields.
 
NOTE You can query all stored fields using field specifiers in field text queries. You can also query Index fields using text queries.
