document_id globally incrementing
...would expect.
So far all good.
Here is the problem: when I search through the indexes together (using
database_add_database() on each sub-index), all the document_id:s are
numbered globally, so it seems while writabledatabase_add_document()
reset the document_id counter for each subindex, in the subindexes they
were never reset.
So instead of having 10 sub-indexes with 50 documents in each,
document_id:s ranging from 0-50 in each, I seem to end up with 10
sub-indexes with 50 documents in each, document_id:s ranging from 0-49
in subindex 1, 50-99 in subindex 2, and so on. This would not be a
problem...

avoiding too many loops - reshaping data

Modifying a data frame based on a vector that contains column numbers
Hello!
# I have a data frame:
mydf<-data.frame(c1=rep(NA,5),c2=rep(NA,5),c3=rep(NA,5))
# I have an index whose length is always the same as nrow(mydf):
myindex<-c(1,2,3,2,1)
# I need c1 to have 1s in rows 1 and 5 (based on the information in myindex)
# I need c2 to have 1s in rows 2 and 4 (also based on myindex)
# I need c3 to have 1 in row 3
# In other words, I am trying to achieve this

expression()
Hi,
I'm trying to use expression() to write a text to a graphic in the margin.
Using:
mtext(expression(beta),side=1,line=2)
writes a perfect beta greek character, but I need to add a subindex
"max", and I'm trying:
mtext(paste(expression(beta),"max"),side=1,line=2)
simply writes "beta max" in the plot.
Please, Could you tell me what I'm doing wrong?

Feature request: Determining source index of xapian-compact DatabaseError exception
Greets,
When merging lots of subindexes in batches like so:
xapian-compact -m idx1 idx2... dstidx
Errors such as:
xapian-compact: DatabaseError: Error reading block 0: got end of file
present a problem since it does not provide the offending path name (of the
broken index) for easy identification/removal in automated/batch scenarios...

updating multiple records with form
I have an app that has two models -- products and details. I''m building
a form that allows a user to create a new product and specify a
description, etc.
The form needs to allow for creation of multiple items in the details
model/table. for example, I have a block of form items that collect
info for the men''s version of the product -- inventory count for each
size, etc. And
