public SearchQuery::prepareAndNormalize() Prepares the query and calculates the normalization factor. After the query is normalized the keywords are weighted to give the results a relevancy score. The query is ready for execution after this. Error and warning conditions can apply. Call getStatus() after calling this method to retrieve them. Return value bool TRUE if at least one keyword matched the search index; FALSE if not. File core/modules/search/src/SearchQuery.php, line 391 Class Sea

public SearchQuery::getStatus() Returns the query status bitmap. Return value int A bitmap indicating query status. Zero indicates there were no problems.

protected SearchQuery::parseWord($word) Parses a word or phrase for parseQuery(). Splits a phrase into words. Adds its words to $this->words, if it is not already there. Returns a list containing the number of new words found, and the total number of words in the phrase.

Indicates no positive keywords were in the search expression. Positive keywords are words that are searched for, as opposed to negative keywords, which are words that are excluded. To count as a keyword, a word must be at least \Drupal::config('search.settings')->get('index.minimum_word_size') characters.

Indicates that lower-case "or" was in the search expression. The word "or" in lower case was found in the search expression. This probably means someone was trying to do an OR search but used lower-case instead of upper-case.

Namespace Drupal\search Code const LOWER_CASE_OR = 4;

public SearchQuery::addScore($score, $arguments = array(), $multiply = FALSE) Adds a custom score expression to the search query. Score expressions are used to order search results. If no calls to addScore() have taken place, a default keyword relevance score will be used. However, if at least one call to addScore() has taken place, the keyword relevance score is not automatically added. Note that you must use this method to add ordering to your searches, and not call orderBy() directly, when u

public SearchQuery::execute() Executes the search. The complex conditions are applied to the query including score expressions and ordering. Error and warning conditions can apply. Call getStatus() after calling this method to retrieve them. Return value \Drupal\Core\Database\StatementInterface|null A query result set containing the results of the query.
