MSG_CI_CORRUPT_INDEX_COMPONENT

MSG_CI_CORRUPT_INDEX_COMPONENT is a catalog-integrity event with component and catalog parameters. Those substituted values identify the damaged part of the index and are far more useful than a generic “Windows Search is corrupt” statement.

Preserve the component identifier and first corruption event

Microsoft’s catalog-format documentation describes a catalog as a set of master, shadow, merge-log, index-table, and other components. Corruption of one component can therefore surface during merge or query access without implying that a particular source document is malformed. The correct first split is persistent catalog storage versus repeated corruption introduced after rebuild. Capture the component identity before resetting the catalog, because the reset can remove the evidence needed to see that pattern.
