It sounds OK for me.
One month ago, I look at swish-e to use it for indexing
several databases. It was a small and very nice package,
well implemented, simple to modify and with some cgi scripts.
But, it had not phrase searching ... and I need it.
I took a look at the code and I thought it was easy to
add this feature.
But when I began working, looking at the code, I saw that
not all patches had been applied, there were many memory
leaks and some of the code could be really improved for
better performance and better portable storage.
Perhaps I am making many modifications with the only advice
of Bill Moseley and SRE. So, it is time to stop and redefine
where do we want to go.
Since my last message to this list, I have added the following
new features and patches:
- Better compression scheme. In my own test case I save up
to 25 % of disk space. I think compress was using an unneded
null extra byte.
- More portable "DOC PROPERTIES". Now, the integers are
stored in the portable format of compress function. So, the
final index file is "more portable" between platforms. May
I say "portable" instead of "more portable"?
- Compress function is now implemented as a macro. Now
indexing is faster.
- Sorting of results by properties (-s option). -s is for
sort. Only descending sort is implemented but you can use
more than one property.
Make it ascend will be very simple if it is considered
useful. The sort implementation is just based in qsort
and strcasecmp. You can sort by date if you store it in
- Show a range of results (-b option) based on patch from
Scott Schultz. (-b is for begin). Combined with -m you
can get m results starting at b.
- More working in memory.
These all are not available because I am testing them at
this moment. Give me one day and I will make it available.
Some other patches to add:
- Filter patch from Rainer Scherg.
To do (this comes to my mind at this moment):
- Better "or". When long results are returned it is slow
(This is the case of search of the type a* or b* or c*...)
I am not sure if it will worth the effort.
- Better phrase search. Stopwords, colons etc. what to do
- A near operator?
- An apache module? (This needs more working on memory.
We must free ALL the memory used by each search).
- A get_document function for highlighting words?
- All words are treated as a string in de index file. Can
we add a numeric data type to the index? This can help in
searching with <, <=, =,>=,> for numbers and dates
(stored as a number).
Waiting to hear from all of you...
