+:py:mod:`ldap.filter` LDAP filter handling
+============================================
+
+.. py:module:: ldap.filter
+   :synopsis: LDAP filter handling.
+.. moduleauthor:: python-ldap project (see http://www.python-ldap.org/)
+
+
+.. % Author of the module code;
+
+
+.. seealso::
+
+   :rfc:`4515` - Lightweight Directory Access Protocol (LDAP): String Representation of Search Filters.
+
+The :mod:`ldap.filter` module defines the following functions:
+
+
+.. function:: escape_filter_chars(assertion_value[, escape_mode=0])
+
+   This function escapes characters in *assertion_value* which  are special in LDAP
+   filters. You should use this function when  building LDAP filter strings from
+   arbitrary input.    *escape_mode* means:  If :const:`0` only special chars
+   mentioned in RFC 4515 are escaped.  If :const:`1` all NON-ASCII chars are
+   escaped.  If :const:`2` all chars are escaped.
+
+   .. % -> string
+
+
+.. function:: filter_format(filter_template, assertion_values)
+
+   This function applies :func:`escape_filter_chars` to each of the strings in
+   list *assertion_values*. After that *filter_template* containing  as many
+   :const:`%s` placeholders as count of assertion values is  used to build the
+   whole filter string.
