[MarkLogic Dev General] lib-search, Fields, andcts:field-word-query

[Shannon Scott Shiflett]

Dear John,

I use lib-parser, not lib-search, but in case the concept is similar,  
this is the conditional code block in one of our programs in which if  
the user has selected "docs" as their search scope then a fielded  
search becomes the default without requiring the user to know or  
supply a field name:

else if ($scope = "docs") then (
     (: use cts:field-word-querys and fields for document-only search :)
     (: get a cts:query type from query string :)
     let $cts-query := lp:get-cts-query($phrase)
     (: get a cts:query element from cts:query constructor :)
     let $cts-query-element := lp:serialize-cts-query($cts-query)
     (: turn the cts:query element into a string :)
     let $cts-query-element-string := xdmp:quote($cts-query-element)
     (: replace every cts:word-query with a sequence of cts:field-word- 
querys :)
     let $cts-query-element-string-fields := replace(
       $cts-query-element-string,
       '<cts:word-query(.*?)>(.*?)</cts:word-query>',
       '<cts:field-word-query $1 string-item="div_nonotes">$2</ 
cts:field-word-query>'
     )
     (: change the string back into a cts:query element :)
     let $cts-query-element-fields := xdmp:unquote($cts-query-element- 
string-fields)
     (: convert the cts:query element into a cts:query constructor :)
     let $cts-query-final := lp:deserialize-query($cts-query-element- 
fields)
     return $cts-query-final (: return the constructor :)

Basically, using regex the cts:word-query() is translated into a  
cts:field-word-query().

This was pre-conference, and I do not know if this applies to your  
case at all or is at all helpful, and I'd be interested in hearing  
from others whether this method has any merit or if there is a more  
direct approach.

Regards,
Shannon
