Knowledge Base Re-Index

The following changes made to search settings require that you re-index the knowledge base using the Knowledge Re-index utility:

• After importing knowledge
• After changing parse settings
• After mass deletions
• When search failures occur

Re-indexing is necessary because existing documents do not reflect any changes made to the synonyms, noise words, special terms, and other research parameters until they have been re-indexed. All new synonyms, noise words, and special terms must be re-indexed to help ensure that keyword searches of the knowledge base are current and accurate.

You run Knowledge Re-index from a command line. pdm_k_reindex.exe is the executable file for Knowledge re-index.

Note: Re-indexing the documents in the knowledge base can be a time-consuming operation, depending on the size of your database. We recommend that you run the Knowledge Re-index utility after all changes have been added.
