Need help Migrating to Solr

[Abin Mathew]

Hi

I am new to the solr technology. We have been using lucene for handling
searching in our web application www.toostep.com which is a knowledge
sharing platform developed in java using Spring MVC architecture and iBatis
as the persistance framework. Now that the application is getting very
complex we have decided to implement Solr technology over lucene.
Anyone having expertise in this area please give me some guidelines on where
to start off and how to form the schema for Solr.

Thanks and Regards
Abin Mathew

Newbie Question on Custom Query Generation

[Abin Mathew]

Hi I want to generate my own customized query from the input string entered
by the user. It should look something like this

*Search field : Microsoft*
*
Generated Query*  :
description:microsoft +((tags:microsoft^1.5 title:microsoft^3.0
role:microsoft requi
rement:microsoft company:microsoft city:microsoft)^5.0) tags:microsoft^2.0
title:microsoft^3.5 functionalArea:microsoft

*The lucene code we used is like this*
BooleanQuery must = new BooleanQuery();

addToBooleanQuery(must, "tags", inputData, synonymAnalyzer, 1.5f);
addToBooleanQuery(must, "title", inputData, synonymAnalyzer);
addToBooleanQuery(must, "role", inputData, synonymAnalyzer);
addToBooleanQuery(query, "description", inputData, synonymAnalyzer);
addToBooleanQuery(must, "requirement", inputData, synonymAnalyzer);
addToBooleanQuery(must, "company", inputData, standardAnalyzer);
addToBooleanQuery(must, "city", inputData, standardAnalyzer);
must.setBoost(5.0f);
query.add(must, Occur.MUST);
addToBooleanQuery(query, "tags", includeAll, synonymAnalyzer, 2.0f);
addToBooleanQuery(query, "title", includeAll, synonymAnalyzer, 3.5f);
addToBooleanQuery(query, "functionalArea", inputData, synonymAnalyzer,);
*
In Simple english*
addToBooleanQuery will add the particular field to the query after analysing
using the analyser mentioned and setting a boost as specified
So there "MUST" be a keyword match with any of the fields
tags,title,role,description,requirement,company,city and it "SHOULD" occur
in the fields tags,title and functionalArea.

Hope you have got an idea of my requirement. I am not asking anyone to do it
for me. Please let me know where can i start and give me some useful tips to
move ahead with this. I believe that it has to do with modifying the XML
configuration file and setting the parameters in Dismax handler. But I am
still not sure. Please help

Thanks & Regards

Hi, I realized the power of Dismax Query Handler recently and now I
dont need to generate my own query since Dismax is giving better
results.Thanks a lot
