Schema for indexing PDF/Doc/XLS files
Hello, I just got the example of Solr 1.4 and Jetty running nicely, as expected. I'm trying to design my Schema at the moment. My goal is to index PDF/Doc/XLS files with the following fields: 0. ID number 1. Filename 2. File path 3. Modification date 4. File contents 5. Number of pages - Any tips on what type of fields should I use to get this data indexed? - Is there a way to get the ID number incremented automatically by Solr, each time a document is added to the index? - Would I be able to extract the information above using just the Solr/Tika features? Or would I have to source all values myself, except "file contents" and pass them to solr when indexing? Thank you much. Regards, Veselin K
Pass Double Quotes using SolrJ
Hi, I want to pass double quotes to my solr from the front end, so that it can return the specific results of that particular phrase which is there in double quotes. If I use httpClient, it doesnt allow me to send the query in this format. As it throws me an invalid query exception. I want to know, if I can do this with SolrJ Client. If yes, can somebody please let me know as how SolrJ is doing this and parsing this type of query.

Re: Composite POJO support
Hi Noble,
Storing fields as Strings means I have to use a POJO for this activity
right? If so I am done.
But according to your suggestion "Let the FieldType in Solr parse and create
appropriate data structure".
How am I going to do this? Am very new to Solr. So please don't mind if I
dumb questions.
Please give some sample example if possible.

Re: Composite POJO support
OK . That is not a good solution.
In Solr, you can only have a flat document structure. Where each field
is a primitive (String, Number, Date) or a List of primitives.So, the
SolrJ API only supports these . You may really not need a Custome
type.

it does not have to.
composite types are not supported.because Solr cannot support that.
But the field can be a List or array.
