Build Index: Full creates which of the following?

• A. Updates an index after adding or removing documents.
• B. Creates a full build of the index.
• C. Compresses all sub-indexes by fragmentation.
• D. Deactivates the index from the search menu.

Answer: (B)

A full build means creating a complete, from-scratch reindexing of every document in the collection. It reconstructs all the data structures used for searching—term dictionaries, frequencies, and postings—so the index reflects every bit of content as if you started fresh. That’s why this option best describes creating a full build of the index: it performs a complete rebuild rather than just incorporating recent changes. In contrast, updating after adding or removing documents is an incremental process that only handles changes since the last build, not a full reconstruction. Compressing all sub-indexes by fragmentation is about optimizing and reducing fragmentation, not about rebuilding the entire index. Deactivating the index from the search menu disables access to that index, rather than building or rebuilding it. A full build is typically used when you need full consistency across the entire index, such as after major content changes or potential index corruption, though it takes longer than incremental updates.
