I think I've achieved a 1% familiarity with MarkLogic now ! Its
exciting !
Now to get to 2% I have a question which is either obvious or impossible
:) Ok 2 questions !
I've been playing with cts:search(). Amazing. I can search 1GB of XML
for matches and get results in < .2 secs wow.
Ok now that I"m impressed I *want more !*
Q1: (easy I hope)
How can I do a search for not only an exact term but a total text
content.
For example I'm doing this query
cts:search(/hl7:document , cts:word-query( $term ,
"exact" ) )
If term is say "AMA" then it matches an "AMA" in any element even if its
part of a sentence like
<text>Published by the AMA</text>
This is great. But what if I want an *exact total text equality* match,
that is only match
<some_element>AMA</text>
The xpath would be
//node()[text() eq $term]
Is there a cts:search for that ? Or should I just use the xpath ?
I like the cts:search() because then I can do pagination on it
efficiently.
Q2: (harder)
Suppose I do a search or other extraction and get a string like
"Take two aspirin or codeine and call me in the morning"
I would like to search this entire string and find matches where any
word in the string is an exact match to some criteria.
A pseudo code might be
for $word in fn:tokenize( $text , " " )
return cts:search( // , $word )
But I'm sure thats slow as hell. Is there a direct function to do
this kind of thing ? I cant find one.
For example I might locate a match for "aspirin" and "codeine".
Similar to Q1: I'd like to restrict these matches to whole exact matches
so I dont find things like "take" and "morning".
Thanks for any suggestions on where to look !
