- Supported are: No truncation(100) which is the default,
- Right trunation(1), Left truncation(2),
- Left&Right truncation(3),
- Process <literal>#</literal> in term(100) which maps
- each # to <literal>.*</literal>,
- Regexp-1(102) normal regular, Regexp-2(103) (regular with fuzzy),
+ The truncation attribute specifies whether variations of one or
+ more characters are allowed between serch term and hit terms, or
+ not. Using non-default truncation attributes will broaden the
+ document hit set of a search query.

+ <para>
+ Truncation attribute value
+ <literal>Regexp-1 (102)</literal> is a normal regular search,

+ <para>
+ Truncation attribute value
+ <literal>Regexp-2 (103) </literal> is a Zebra specific extention

+ change of posiiton.
