I have a requirement to group documents by count based on a particular field:
So for example if you have the following three documents:
<doc>
<id>1</id>
<category>food</category>
<body>car</body>
</doc>
<doc>
<id>2</id>
<category>travel</category>
<body>car</body>
</doc>
<doc>
<id>3</id>
<category>food</category>
<body>car</body>
</doc>
A search with the query string 'car' based on a grouping based on the
'category' field should return something like:
<doc>
<id>1</id>
<category>food</category>
<body>car</body>
<category_count>2</category_count>
</doc>
<doc>
<id>2</id>
<category>travel</category>
<body>car</body>
<category_count>1</category_count>
</doc>
<doc>
<id>3</id>
<category>food</category>
<body>car</body>
<category_count>2</category_count>
</doc>
Is this possible?
Regards,
Sreekant
