Re: How does delete work?

So what if documents are deleted in the meantime? Then the recursive merge
can't determine the X segments with the same size.

Re: Problem with Range

Correct but actually it would be  ( DATE:[null - 20020101])  with spaces
around the -.

 This probably does not answer your question, but may be a side effect:

if(start!=null || end!=null){
  buff.append( ( DATE:[);
  buff.append(start);
  buff.append( - );
  buff.append(end);
  buff.append(] ) );
  fieldList.add(DATE);

 This implies that start OR end can be null, producing something like (
 DATE:[null-20020101])

If you read my previous message you'll find the answer:

 It's actually a little more complicated than that, since (among other
 reasons) after docuuments are deleted a segment's size will no longer
 be exactly a power of the mergeFactor.

If you want the gory details, look at IndexWriter.java.  Or just set 
IndexReader.infoStream to System.out, then add and delete documents and 
watch what happens.

Does anyone have a handy library to compute readability score?


Here is an extract from a paper describing the Flesch index and an  
algorithm to count syllables... Does that make any sense?

Thanks.

 ... Each vowel (a, e, i, o, u, y) in a word counts as one syllable  
subject to the following sub-rules: Ignore final -ES, -ED, -E (except

Consecutive vowels count as one syllable. Although there are many
