Fulltext query: values in some elements are not indexed?
We query on fulltext an xml file. After some experiments we found out that if the "terms" are in the middle of the text-element the 'ft:contains' returns true. On the other hand, if the query is the whole text-element it returns false. ie. <ows:IndividualName>FirstName LastName</ows:IndividualName> the query -------- query -------- for $r in /server where ft:contains($r, ( 'FirstName' , 'LastName' ), <options><fuzzy value="true"/><mode value='any'/></options>) return $r --- end of query --- returns an empty set. In addition, queries with fuzzy value equal to false or true and mode value phrase return also an empty set. Regards Yannis
Hi Ioannis, could you please provide us with a fully working example? If you work with mixed content, you could as well have a look at our documentation [1].

Hello Christian, Thank you for the quick reply. This is the document I am trying to query: http://ariadni.di.uoa.gr:8181/BaseX78/rest/wcs-collection/bgs.xml it's not mixed. if the terms are: "services for the" it returns results... if the terms are "John Laxton", it will return an empty set.

If all of the terms you are looking for occur in the same text node, you can try the following query: for $r in /server where ft:contains($r//text(), ( 'John Laxton' )) return $r As an alternative, you can to deactivate whitespace chopping before creating a document [1]. Otherwise, empty text nodes will be removed from your document, and your text nodes will be merged. This is demonstrated by the following two queries: ft:contains(<a>A<b>X</b></a>, 'A') ft:contains(<a>A<b>X</b></a>, 'AX') Hope this helps, Christian [1] http://docs.basex.org/wiki/Options#CHOP On Mon, Mar 10, 2014 at 11:03 AM, Ioannis Kavvouras <i.kavvouras@di.uoa.gr> wrote:

for $r in /server where ft:contains($r//text(), ( 'John Laxton' )) return $r this worked in all cases :)
