A developer decides to use a text pre-extraction for re/indexing Lucene indexes.

Text pre-extraction is recommended during reindexing of existing Lucene indexes that have binary extraction enabled. Binary extraction is the process where text content is extracted from binary files (such as PDFs or Word documents) for indexing. During reindexing, extracting text repeatedly from large binaries can cause performance degradation. Pre-extraction allows text to be extracted once and reused during indexing, significantly reducing reindexing time and system load. Option B is incorrect because small repositories don’t require pre-extraction optimization. Option C is also incorrect, as images generally don’t involve binary text extraction unless paired with OCR. Adobe highlights pre-extraction as a performance optimization technique for reindexing scenarios involving binary text content.
