+The command
+.B soundex
+creates a secondary index to
+.I file
+based on Knuth's soundex code.
+It is used by the
+.B /rdb
+command
+.B like
+to find a name that sounds like another name.
+.PP
+The output must be written into file
+\fIfile\fB.x\fR; then run the command
+.B index
+on column
+.B Soundex
+within
+.IB table .x
+to ensure a high-speed search.
+.SH Example
+Consider table
+.BR name ,
+which has many similar names in it:
+.DM
+Name
+----
+Abraham
+Abraham
+Ackerman
+Actor
+Adams
+Adams
+Adams
+Adams
+\&...
+.DE
+.PP
+Use
+.B soundex
+to create the secondary index file, as follows:
+.DM
+	soundex < name > name.x ; index -mb name.x Soundex
+.DE
+.PP
+The soundex'd index file appears as follows:
+.DM
+.ta 1.0i
