Standard query parser does not throw any syntax error. So, identifying syntax errors is a little tough.
The following parameters are supported by standard query parser. We can configure them in solrconfig.xml:
|
Parameter |
Behavior |
Default value |
|
q |
Specifies a query using standard query syntax. This is a mandatory parameter for any request. |
|
|
q.op |
Specifies the default operator for query expressions, which overrides the default operator configured inside the schema. Possible values are AND or OR. |
|
|
df |
Specifies a default field, which overrides the default field definition inside the schema. |
|
|
sow |
If this is set to true, it splits on white spaces. |
false |
Standard query parser response: The following is the sample response provided by the standard query parser when we search for field id=SP2514N
URL: http://localhost:8983/solr/techproducts/select?q=SP2514N&wt=json
In Solr admin console, while running a query to search a product with id=SP2514N displays the response as follows:
The response code is as follows:
{
"responseHeader":{
"status":0,
"QTime":0,
"params":{
"q":"SP2514N",
"wt":"json",
"_":"1515346597997"}},
"response":{"numFound":1,"start":0,"docs":[
{
"id":"SP2514N",
"name":"Samsung SpinPoint P120 SP2514N - hard drive - 250 GB - ATA-133",
"manu":"Samsung Electronics Co. Ltd.",
"manu_id_s":"samsung",
"cat":["electronics",
"hard drive"],
"features":["7200RPM, 8MB cache, IDE Ultra ATA-133",
"NoiseGuard, SilentSeek technology, Fluid Dynamic Bearing (FDB) motor"],
"price":92.0,

"price_c____l_ns":9200}]
}}
In the same way, now the query id=SP2514N; and we need only two fields, id and name, in response.
URL: http://localhost:8983/solr/techproducts/select?fl=id,name&q=SP2514N&wt=json.
Response:
{
"responseHeader":{
"status":0,
"QTime":17,
"params":{
"q":"SP2514N",
"fl":"id,name",
"wt":"json",
"_":"1515346597997"}},
"response":{"numFound":1,"start":0,"docs":[
{
"id":"SP2514N",
"name":"Samsung SpinPoint P120 SP2514N - hard drive - 250 GB - ATA-133"}]
}}
We can format the response by setting the wt parameter as json, xml, xslt, javabin, geojson, python, php, phps, ruby, csv, velocity, smile, or xlsx.
