Index Fields
Store fields that contain text which you want to query frequently as Index fields. Index fields are processed linguistically when they are stored in IDOL server. This means stemming and stop word lists are applied to text in Index field before they are stored, which allows IDOL server to process queries for these fields more quickly (typically DRETITLE and DRECONTENT are fields that are set up as Index fields).
Do not store URLs or content that you are unlikely to use in Index fields. Additionally, do not store fields as Index fields that are queried frequently, but whose values are queried only in their entirety. It is more efficient to query such values using a field specifier (for example, MATCH).
Also, do not store fields that contain numeric values or dates as index fields. Instead store these fields as numerical fields and numeric date type fields.

To set up Index fields
1.
2.
List an indexing process in the [FieldProcessing] section. For example:
[FieldProcessing]
0=MyFirstProcess
1=MySecondProcess
2=IndexingFields
3.
Create a section for the indexing process, and in each section, create a property for the process (a property is later defined by one or more applicable configuration parameters). Identify the fields you want to associate with the process.
You can use the PropertyMatch parameter to identify a specific value that fields must have to be processed.
 
NOTE The properties you create must not have the same name as the processes.
For example:
[MyFirstProcess]
Property=MyFirstProperty
PropertyFieldCSVs=*/MyField,*/MySecondField
PropertyMatch=*myString*
[MySecondProcess]
Property=MySecondProperty
PropertyFieldCSVs=*/MyOtherField,*/MyOtherSecondField
[IndexingFields]
Property=IndexFields
PropertyFieldCSVs=*/DRECONTENT,*/DRETITLE

[MyFirstProperty]
HiddenType=true
[MySecondProperty]
Index=true
[IndexFields]
Index=true
