Regular expression error: Regular expression too complex. reserved reserved. err insert (x,y) reserved ^p1^: Need CR to end the line Bad examples: "AA" "aa" cc Try "AA" "aa" % cc Need a close ^p1^ Bad example: "AA" "aa % Try:"AA" "aa" If the filter looks like “no error”, it may contain some control characters. ^p1^: Need an open " ' or $ Bad examples: AA aa % try "AA" "aa" "AA" aa % try "AA" "aa" If the filter looks like “no error”, it may contain some control characters. Define error. List of define: #meta "/" % use / as meta #meta "" % do not meta #type 1 % filter type I #type 2 % filter type II See also: "Filter Syntax Reference" Second string can't to be regular expression. Bad examples: "ABC" 'abc' Try: "ABC" "abc" ^p1^: Digit error in dec/hex/oct number. Bad examples: "\dz" "K" % must be \d1-\d255 "\xXY" "K" % must be \x00-\xFF "ABC" "abc" (K, 1) % K: not a number See also: "Filter Syntax Reference" Can not set this filter to type I.

List of special characters: \\, \", \*, \t, \n, \r, \d, \x, \o, \>. See also: "Filter Syntax Reference". The string is too long. 1. One line must have less than 4096 characters. 2. For type II filter, the second string must have less than 32 characters. Note that adding a line like "AA" "AA" turn this filter to type I.(See "Technical Note")
