Each document store’s collection of index stripes contain zero or more static index stripes. A static index stripe is a collection of disk-oriented data structures, which you cannot change once written.
Each static index stripe directory contains the form IS-#, where # is a unique stripe ID. Each index stripe contains the following directories and files:
doc – directory that contains a proprietary data structure used to store document information used in query calculations.
metadata – directory that contains a proprietary data structured used to store metadata information used in query calculations.
term – directory that contains a proprietary data structure used to store body text information used in query calculations.
common-docroot.txt – absolute path to the directory root common to all indexed directories. For example, C:\office\sales and C:\office\marketing have a common document root of C:\office.
del.lex – contains statistical data on deleted documents not yet purged.
deleted.ser.gz – contains deleted document identifiers.
di-inf.ser.gz – the document index meta information.
lengths.ser.gz – the document length (or term count) for each indexed document.
