some basic information on Solr
Hi all,
I am doing a student project on search engine research. Right now I have
some basic questions about Slor.
1. How many types of data file Solr can support (estimate)? i.e. No. of
file types solr can look at for indexing and searching.
2. How much is estimated cost of incidents per year for Solr ?
Since the numbers could vary from different platforms, however we would like
to know the estimate answers regarding the general cases.
Thanks

It didn't look like that, but.... maybe.
Our experience has been very very good. I don't think we have seen a crash in our prototype to date (though that prototype is also not very busy). We have had as many a four cores, with as many as 35 million "documents".

i think with "incident" he mean, failures / downtimes / problems with solr !?

basically you can use solr to index all kinds of documents as long as
you can extract the text from the document. However, Solr ships with
content extraction support that handles a large set of different
files. AFAIK it leverages apache tika (http://tika.apache.org) which
supports a very large set of document formats
(http://tika.apache.org/0.10/formats.html). Hope this helps here?!

I have to admit I don't know what you are asking for. can you
elaborate on this a bit? What is an incident in this context?

I am not a developer either. We are just using it in a project here.

JRJ,
We did check the solr official website but found it was really technical,
since we are not on the developer side and we just want some basic
information or numbers about its usage.
Thanks for your answer, anyway.

1. Solr, proper, does not index "files". An adjunct called Solr Cel can. See http://wiki.apache.org/solr/ExtractingRequestHandler . That article describes which kinds of files it Solr Cel can handle.
2. I have no idea what you mean by "incidents per year". Please explain.
3. Even though you didn't ask: You are apparently a student at an advanced level. At your level I would guess that your professors expect *YOU* to read thru the material available on the Internet on Solr and figure it out on your own, rather than just asking others to do your work for you. ;^)
