.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
An InvIndex is an abstract representation of an inverted index, KinoSearch's
core data structure.  The archetypal implementation of an invindex,
FSInvIndex, is a single directory holding a collection of files.  However, to
allow alternative implementations such as RAMInvIndex, i/o and file
manipulation are abstracted out rather than executed directly by KinoSearch's
classes.
.PP
A \*(L"file\*(R" within an invindex might be a real file \*(-- or it might be a ram file,
or eventually a database record, etc.  Similarly,
\&\f(CW\*(C`$invindex\->delete_file($filename)\*(C'\fR might delete a file from the file
system, or a key-value pair from a hash, or something else.
