Hi Danny,
There's no way to build an index on your XML below that will result in "John R.
Smith" as a value. The common approach is to adjust your data to something like:
<contrib contrib-type="author">
<name full="John R. Smith">
<surname>Smith</surname>
<given-names>John R.</given-names>
</name>
<degrees>Ph.D.</degrees>
</contrib>
Alternatives… you could muck around with things at run time. If you wanted to
search for "John R. Smith" as an author, you could do a custom constraint that
breaks up the string into given-name and surname parts, then does an and-query
(or near-query, if you could have more than one author in a document).
If you want to build a facet on those values, you could try either a custom
facet the uses co-occurrences (specify proximity=1 to make sure you don't get
combinations of all authors), or you might be able to build a UDF to do the
same thing. In either case, you'd have to watch for multiple authors messing
you up, and I'd expect either approach would be slower than combining the
values ahead of time and being able to set up a single index (like name/@full
above).
Dave.

Subject: [MarkLogic Dev General] Lexicon for author names
I'd like to create a lexicon for author names but our XML structure for those
names goes like this :
<contrib contrib-type="author">
<name>
<surname>Smith</surname>
<given-names>John R.</given-names>
</name>
<degrees>Ph.D.</degrees>
</contrib>
Is it possible to create a single path range index ?
If so, how do I formulate the XPath for the index ?
And once the index is created, how do I express the author name in the $value
parameter to a call to cts:path-range-query () ?
Regards,
Danny
