Search Engine Text Extraction
The search engine will use the text file associated with a document if one exists. Search engine text extraction is only used if no such file exists. In most cases, we recommend generating text on electronic documents in client applications rather than relying on the search engine, as search engine text extraction can slow indexing and must be re-done whenever the document is reindexed.
Note: Search engine text extraction has no effect on imaged documents.
Information about IFilters is available in Knowledge Base article 1011194 INFO: Retrieving Text from Electronic Files with IFilters. Note that you will need to install the correct IFilters on the computer on which the Laserfiche Full-Text Indexing and Search Service is installed. Search engine text extraction will only work for file types that have text associated with them. Files that have no text (for instance, images, or PDFs containing no text) cannot be made searchable in this way.
Note: Before determining what IFilters you might need, we recommend consulting the Electronic Text Extraction list in the Laserfiche desktop or Web Administration Console to view what types of files the Laserfiche Full-Text Indexer can extract text from by default. If a file type is on the list, the Laserfiche Full-Text Indexer can extract text from and index those types of files.
Note: If you are using Laserfiche QuickReindex to index your documents, IFilters must be installed on both the Laserfiche Full-Text Indexing and Search Engine computer and the Laserfiche Server computer.
