two structures in solr
Hi all,
I'm a solr newbie, so sorry if I do anything wrong ;)
I want to use SOLR not only for fast text search, but mainly to create a
very fast search engine for a high-traffic system (MySQL would not do the
job if the db grows too big).
I need to store *two big structures* in SOLR: projects and contractors.
Contractors will search for available projects and project owners will
search for contractors who would do it for them.
So far, I have found a solr tutorial for newbies
http://www.solrtutorial.com, where I found the schema file which defines the
data structure: http://www.solrtutorial.com/schema-xml.html. But my case is
that *I want to have two structures*. I guess running two parallel solr
instances is not the idea. I took a look at
http://svn.apache.org/viewvc/lucene/dev/trunk/solr/example/solr/conf/schema.xml?view=markup
and I can see that the schema goes like:
<?xml version="1.0" encoding="UTF-8" ?>
<schema name="example" version="1.5">
<types>
...
</types>
<fields>
<field name="id" type="string" indexed="true" stored="true"
required="true" />
<field name="sku" type="text_en_splitting_tight" indexed="true"
stored="true" omitNorms="true"/>
<field name="name" type="text_general" indexed="true" stored="true"/>
<field name="alphaNameSort" type="alphaOnlySort" indexed="true"
stored="false"/>
...
</fields>
</schema>
But still, this is a single structure. And I need 2.
Great thanks in advance for any help. There are not many tutorials for SOLR
in the web.

there's nothing wrong with it, the real question is wether you ever need
to do things with both sets of documents at once.
if contractors only ever search for projects, and project owners only ever
serach for contractors, and no one ever searches for a mix of projects and
contractors at the same time, then i would just suggest using multiple
SolrCores...

bq: Is that right?
I don't know, does it work <G>? You'll probably want an
additional field for unique id (just named "id" in the example)
that should be disjoint between your types.

Thank you very much Erick for your reply!
So should it go something like the following:
http://lucene.472066.n3.nabble.com/file/n3907393/solr_index.png
sorry for an ugly drawing ;)
In this example, the index will have 13 columns: 6 for project, 6 for
contractor and one to define the type. Is that right?

You have to take off your DB hat when using Solr <G>...
There is no problem at all having documents in the
same index that are of different types. There is no
penalty for field definitions that aren't used. That is, you
can easily have two different types of documents in the
same index.
It's all about simply populating the two types of documents
with different fields. in your case, I suspect you'll have a
"type" field with two valid values, "project" and "contractor"
or some such. Then just attach a filter query depending on
what you want, i.e. &fq=type:project or &fq=type:contractor
and your searches will be restricted to the proper documents.
