I'm using Apache Solr for search.I import data from mysql table using data import handler.But when i use q=KOHLI insted of q=lastname:KOHLI ,i didn't get any results.

Here is response for q=lastname:KOHLI

{
  "responseHeader": {
      "status": 0,
      "QTime": 1,
      "params": {
      "q": "lastname:KOHLI",
      "indent": "true",
      "wt": "json",
      "_": "1427802213299"
    }

  "response": {
     "numFound": 1,
     "start": 0,
     "docs": [
      {
        "lastname": "KOHLI",
        "town": "DELHI",

schema.xml:

<copyField source="firstname" dest="text"/>
<copyField source="lastname" dest="text"/>

<field name="lastname" type="text_general" indexed="true" stored="true"/>
<field name="town" type="text_general" indexed="true" stored="true"/>`

Answer 1

Are you using a query parser? If yes, in your file solrconfig.xml , what is the query field that you are using inside your requestHandler ? ( qf parameter). If you don't have your field lastname , here it's a normal behaviour.

If you don't use a query parser, in your file schema.xml , what is your defaultSearchField ?

Can you add snippets of your Solr's files?

Answer 2

When you don't specify a field for the search, it searches the default search field. If you want to perform a search like that, you may create new field and copy all other fields that you want to make them a target for search to that field, then set it as default search field.

Here are some resources:

• CopyField
• DefaultSearchField

Answer 3

This is because you did not set default search field correctly. If you did not pass a field name in "q", it will search input to default field, which you set in config file for your project.

To set default field, you can do either way:

1. In your schema.xml, change <defaultSearchField>id</defaultSearchField> to <defaultSearchField>lastname</defaultSearchField>

2. Run with q={!type=dismax qf=lastname}KOHLI in your q (remove "q=" if in web port)
