The Zebra information server combines a versatile fielded/free-text
search engine with a Z39.50-1995 frontend to provide a powerful and flexible

+Indexing is a per-record process, in which either insert/modify/delete
+will occur. Before a record is indexed search keys are extracted from
+whatever might be the layout the original record (sgml,html,text, etc..).
+The Zebra system currently supports two fundamantal types of records:
+structured and simple text.
To specify a particular extraction process, use either the
command line option <tt>-t</tt> or specify a
<tt>recordType</tt> setting in the configuration file.
<bf/Completeness/ attribute of <bf/Complete (Sub)field/, the term is
matched against the contents of the phrase (long word) register, if one
exists for the given <bf/Use/ attribute.
-A phrase register exists for those fields in the <tt/.abs/
+A phrase register is created for those fields in the <tt/.abs/
file that contains a <tt/p/-specifier.
If <bf/Structure/=<bf/Phrase/ is used in conjunction with
<sect3>Query examples
<p>
+
Phrase search for <bf/information retrieval/ in the title-register:
<verb>
@attr 1=4 "information retrieval"
@attr 1=4 @attr 5=102 @attr 2=102 "informat.* retrieval"
</verb>
-Relational search on a numeric index (westoundingCoordinate > -114):
+In the GILS schema (<tt/gils.abs/), the west-bounding-coordinate is
+indexed as type <tt/n/, and is therefore searched by specifying
+<bf/structure/=<bf/Numeric String/.
+To match all those records with west-bounding-coordinate greater
+than -114 we use the following query:
<verb>
@attr 4=109 @attr 2=5 @attr gils 1=2038 -114
</verb>
