Requirements

Search a string (whole/part/regex) in a field of partilcular type of document in a particlur container.

• If the size of whole content is small and never going to grow or there won't be heavy requests we can go for a simple lookup using a looping function (may be recursive)
• If the size of whole content is medium and never going to grow or there won't be heavy requests we can go for a simple catalog (which one? hurry) This will be the most common case.
• If the size of whole content is huge and there will be heavy requests we can go for a TextIndexNG3? or external indexing (Lucene,Pylucene)?

Things to look for:

There is something wrong with IntIds? (unique) http://www.zope.org/Collectors/Zope3-dev/466

What does this mean?

• Site Managers are global and local now; adapters and utilties are directly registered with the site manager. Now global and local component registration and lookup behaves very similar.

can I use global utility for indexing a single folder objects?

What about TextIndexNG3?

Lucene and PyLucene?

To check out: $ svn co svn://svn.zope.org/repos/main/zc.catalog

svn co http://codespeak.net/svn/z3/hurry/trunk hurry

A simple usage of catalog

from zope.app.catalog.interfaces import ICatalog
from zope.app import zapi
cat1 = zapi.getUtility(ICatalog, 'cat1') #`cat1` is the name of catalog
result = cat1.searchResults(TextIndex='one') #search `one`
gen = iter(result)
print gen.next()
