/export/scratch0/roberto/lhm/alexandria_doclist.xml contains a list of nodes 
with xml file names. E.g.:

<docs>
<doc>/export/scratch0/roberto/lhm/alexandria/D/1991/EP-0409358-A1.xml</doc>,
<doc>/export/scratch0/roberto/lhm/alexandria/D/1991/EP-0412453-A1.xml</doc>
<doc>/export/scratch0/roberto/lhm/alexandria/D/1991/EP-0453965-A2.xml</doc>
<doc>/export/scratch0/roberto/lhm/alexandria/D/1991/EP-0423091-A2.xml</doc>
</docs>


This used to work (a week ago? I'm not very sure about this). 

[robe...@skadi] ~/lhm_code/HyServer/console
$ echo 'for $i in 
subsequence(doc("/export/scratch0/roberto/lhm/alexandria_doclist.xml")//doc, 1, 
50) return pf:add-doc($i,$i,"alexandria")' | mclient -p 50141 -lxq -d test

[robe...@skadi] ~/lhm_code/HyServer/console
$ echo 'for $i in 
subsequence(doc("/export/scratch0/roberto/lhm/alexandria_doclist.xml")//doc, 
51, 50) return pf:add-doc($i,$i,"alexandria")' | mclient -p 50141 -lxq -d test
MAPI  = mone...@localhost:50141
QUERY = for $i in 
subsequence(doc("/export/scratch0/roberto/lhm/alexandria_doclist.xml")//doc, 
51, 50) return pf:add-doc($i,$i,"alexandria")
ERROR = !ERROR: BATfetchjoin(tmpr_444,tmp_423) does not hit always (|bn|=0 != 
50=|l|) => can't use fetchjoin.
        !ERROR: CMDleftfetchjoin: operation failed.
        !ERROR: interpret_params: shred_doc_base(param 4): evaluation error.

The subsequence call is NOT the proble, it works fine if I just return the $i 
variable.
