Dynamic document structure

[Colin Surprenant]

Hi,

I am currently evaluating Xindice for my project and I have a few questions 
before moving on and trying it.

1- When creating a collection, are there any restrictions on each document 
structure within the same collection? For example, if my collection is a 
contact list where each document is a single contact and my first contact 
document looks like this:

<contact>
  <name>...</name>
  <home-phone>...</home-phone>
</contact>

then my second contact document looks like this :

<contact>
  <name>...</name>
  <cell-phone>...</cell-phone>
  <email>...</email>
</contact>

Will it still be possible the create indexes on such a collection on a tag that 
migh not be present in all documents?

2- Are there any restrictions on the number of documents in a collection? Is it 
an acceptable design in Xindice to create a collection that will handle a very 
large number of small documents? (for example in the order of hundreds of 
thousands of documents), what about performace?

Thanks for your input.
