I have configured solr, such that, it can index records from postgres database. It's uploaded successfully. And if I pass query string as `*:*`, it produce a response of all rows in the table. But when i specify the search, the result is always 0.

My XML response when query string `*:*` is:

```
<?xml version="1.0" encoding="UTF-8" ?> 

<response>
  <lst name="responseHeader">
   <int name="status">0</int> 
   <int name="QTime">0</int> 
   <lst name="params">
      <str name="q">*:*</str> 
   </lst>
 </lst>
 <result name="response" numFound="3" start="0">
 <doc>
<str name="names">sample1</str> 
<str name="sno">1</str> 
<str name="values">3</str> 
</doc>
 <doc>
<str name="names">sample2</str> 
<str name="sno">2</str> 
<str name="values">2</str> 
</doc>
<doc>
<str name="names">sample3</str> 
<str name="sno">3</str> 
<str name="values">4</str> 
</doc>
</result>
</response>

```

And my response when query string `q=sample1` is:

```
<?xml version="1.0" encoding="UTF-8" ?> 

<response>
  <lst name="responseHeader">
   <int name="status">0</int> 
   <int name="QTime">0</int> 
   <lst name="params">
      <str name="q">*:*</str> 
   </lst>
 </lst>
 <result name="response" numFound="0" start="0" /> 
</response>

```

Thanks in advance.
