Solr search engine need to restart after adding docs - php

Question

I am working with solr 6.6.0 using solr PHP client. I am adding the docs using below code and it is working properly :
foreach ($data as $key => $value) {
$docs['doc_no'.$i]['id'] = $value['id'];
$docs['doc_no'.$i]['name'] = $value['name'];
$docs['doc_no'.$i]['sub_title'] = strip_tags($value['sub_title']);
$docs['doc_no'.$i]['small_image'] = $value['small_image'];
$docs['doc_no'.$i]['project_type'] = $value['project_type'];
$docs['doc_no'.$i]['project_status'] = $value['project_status'];
$docs['doc_no'.$i]['logo'] = $value['logo'];
$docs['doc_no'.$i]['price'] = $value['price'];
$docs['doc_no'.$i]['url'] = $value['url'];
$docs['doc_no'.$i]['flat_type_desc'] = $value['flat_type_desc'];
$docs['doc_no'.$i]['project_config'] = $value['project_config'];
$docs['doc_no'.$i]['address'] = $value['address'];
$docs['doc_no'.$i]['location'] = $value['location'];
$i++;
}
//print_r($docs);exit;
$documents = array();
foreach($docs as $item => $fields) {
$part = new Apache_Solr_Document();
foreach ( $fields as $key => $value ) {
if ( is_array( $value ) ) {
foreach ( $value as $data ) {
$part->setMultiValue( $key, $data );
}
}
else{
$part->$key = $value;
}
}
$documents[] = $part;
}
try {
$solr->addDocuments( $documents );
$solr->commit();
$solr->optimize();
}
catch ( Exception $e ) {
echo $e->getMessage();
}
After executing the above code I have to manually restart the solr through cmd line and then it gets reflected, I want to ask that is every time when I add any docs in solr then I have to restart the solr manually ? Is there any other way to restart the solr automatically as soon as I have the data in docs.
Any help will be appreciated Thanks in advance.

For the submitted documents to be visible in the index, you have to issue a commit - and ask for a new reader to be opened (this is usually handled for you, so that's not usually necessary. How you do exactly that in the Drupal framework I have no idea about, but I'm guessing your Solr client has a commit method or something similar. I tried searching for the API docs, but came up empty except for the _Document class.
After a commit has been issued the index changes will be visible within a few seconds, or in the case of a soft commit (where the changes aren't persisted to disk before later) almost instantly.
You can also ask for a commitWithin interval when submitting documents, but that would also depend on how the client you're using works for how you include that parameter.
