Thanks Jason,
Although I'm more at home using XPath queries, much of what executes needs to be returned in groups. Because of this I'm using cts:search with a constraining queries to perform the filtering. Though I often use XPath on the cts:search results. I have not yet paid enough attention to index options. It does seem that those to options would apply with the cts element queries. gary From: [email protected] [mailto:[email protected]] On Behalf Of Jason Hunter Sent: Tuesday, July 19, 2011 1:46 PM To: General MarkLogic Developer Discussion Subject: Re: [MarkLogic Dev General] Question on fields Besides fields, it's also possible to write queries like this: //Permission[access = "deny" and name = "execute"] MarkLogic can resolve this out of indexes if you have enabled the right position indexes. My notes show you need element-value-positions and word-positions enabled (but I haven't verified myself). This will in some cases be more flexible than fields, such as when you don't know the order of elements. Fields would perform faster as they can avoid the position calculations. -jh- On Jul 19, 2011, at 9:35 AM, Gary Larsen wrote: I need to filter on the data structure below using a combination of both the <name> and <access> values. <permissions> <Permission> <access>deny</access> <name>execute</name> </Permission> <Permission> <access>grant</access> <name>traverse</name> </Permission> </permissions> It seems one way to accomplish this is to create a fragment root on the Permission element. (This would create very large number of fragments.) I also thought that a field defined on the Permission element (the only include, no excludes) would work - as long as the descendant values were always appended in order. For example: cts:field-word-query('permissionField', 'denyexecute') Can I rely on that? Are there other possible solutions?
