+@g@lookbib prints a prompt on the standard error (unless the standard input is not a terminal),
+reads from the standard input a line containing a set of keywords,

+for references containing those keywords,
+prints any references found on the standard output,
+and repeats this process until the end of input.
+For each database

+to be searched,
+if an index
+.IB filename @INDEX_SUFFIX@
+created by
+.BR @g@indxbib (@MAN1EXT@)
+exists, then it will be searched instead;
+each index can cover multiple databases.
+.SH OPTIONS

+.B \-v

+.BI \-i string
+When searching files for which no index exists,
+ignore the contents of fields whose names are in
+.IR string .

+.I n
+characters of keys to be given.
+Initially
+.I n
+is 6.
