Sorry but this does not seem to improve performance, it takes even more
time, have a look at these data:
explain analyze SELECT * FROM ViewHttp
WHERE (vchost || txcontenttype) ilike '%www.%html%'
ORDER BY iDStart DESC, iSensorID DESC, iForensicID DESC, iSubID DESC
OFFSET 0 LIMIT 201

The problem stems from the horrid misestimation of the number of rows
fetched from detail0009:

Hello all,
I'm encountering a quite strange performance problem. Look at the
following two queries and their execution times. The only difference is
the first query has OR operator and the second query has AND operator.
Any ideas?
Thank you in advance,
Federico
[FIRST QUERY: EXEC TIME 0.015 SEC
