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 that stemming and stop word lists are applied to text in Index fields 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 use the Index field type for fields that contain:

  • URLs or content that you are unlikely to use.
  • content that you query frequently, but whose values you query only in their entirety. It is more efficient to use field specifiers (for example, MATCH) to query these values.
  • numeric values or dates as Index fields. Instead, store these fields as numeric fields and numeric date type fields.
