Hi Folks,
I have come across an interesting phenomenon and am trying to understand it.
I have a (range element index) lexicon configured for JournalTitle using the
root collation which contains the following distinct values:
Personality & Individ. Diff.
and
Personality Individ. Diff.
If I perform a lexicon search for "Personality & Individ. Diff." using
cts:element-values() with a subquery of cts:element-value-query() specifying
the equivalent of an exact match in the search options as follows:
element results {
for $result in
cts:element-values(xs:QName("JournalTitle"), (),
("item-frequency", "item-order", "ascending"),
cts:and-query((
cts:element-value-query(xs:QName("JournalTitle"),
"Personality & Individ. Diff.",
("case-sensitive", "diacritic-sensitive",
"punctuation-sensitive", "whitespace-sensitive",
"unstemmed", "unwildcarded"))
))
)[1 to 20]
return element result {$result}
}
then I get the following results (as expected):
<http://markprod.apa.org:8002/eval.xqy?iefix.txt##> - <results>
<result>Personality & Individ. Diff.</result>
</results>
However, if I change the request options to whitespace-insensitive, then I
get the following results:
<http://markprod.apa.org:8002/eval.xqy?iefix.txt##> - <results>
<result>Personality & Individ. Diff.</result>
<result>Personality Individ. Diff.</result>
</results>
This implies to me that the ampersand is treated like whitespace. I would
have expected it to be treated as punctuation, but I'm not sure exactly what
character set (including escaped characters) are defined by whitespace and
punctuation. I've looked into the UCA and ISO-8859-1 specs to try to
understand the default MarkLogic root collation, but I haven't found a
simple list that would help me to understand why I'm getting the above
results. Can anyone shed some light on this?
Can someone also help clarify the distinction between the default MarkLogic
root collation (http://marklogic.com/collation) and the codepoint collation
(http://marklogic.com/collation/codepoint)? I'm trying to find the ideal
collation for my JournalTitle lexicon collation.
Thanks for the help!
