[Exist-open] Indexation questions

[Ariel L. <ar...@ho...>]

Hi All, i have some questions about the way indexation can be made in =
exist.

1) can I specify the order the elements must be indexed? Let's consider =
we have=20
DATA:
 <tag>
  <subtag code=3D"a">AAAAA</subtag>
  <subtag code=3D"b">BBBBB</subtag>
  <subtag code=3D"b">CCCCC</subtag>
  <subtag code=3D"c">DDDDD</subtag>
 </tag>

Currently I can find the string "AAAAABBBBB" with the next query
 //tag[(subtag[(@code=3D'a') or (@code=3D'b')]) and =
contains(.,"AAAAABBBBB")]

But i must find "AAAAACCCCC", "AAAAADDDDD" and "BBBBBAAAAA" too.
It's like an incomplete  catessian product between subtag elements.=20
There is a way to do this?

2) Wich of the next queries is the best (in efficiency)? All queries =
give the same results
//tag[contains(.[(subtag/@code=3D'a') or =
(subtag/@code=3D'b')],"AAAAABBBBB")]
//tag[((subtag/@code=3D'a') or (subtag/@code=3D'b')) and =
contains(.,"AAAAABBBBB")]
//tag[(subtag[(@code=3D'a') or (@code=3D'b')]) and =
contains(.,"AAAAABBBBB")]

3) I'm using latin characters in xml files, but searches must be =
insensible to accents.=20
If i search "caf=E9" matches must be "caf=E9", "cafe", "caf=E8", =
"caf=EB", etc. I can transform
the search term to a String without accents and always search for =
"cafe", while the=20
original search expression be "caf=E9", "cafe" or "caf=E8". But I still =
cant retrive "caf=E9".=20
The best solution could be remove accents from words in index time, so =
index will
recognize only "cafe".

Any answers will be appreciated. Thanks in advance
