will be helpful for those in need Your problem is in operator precedence in your WHERE clause. At present, when $trefwoord is empty, your WHERE clause looks like this:
code :
WHERE cnt.title LIKE '%%' OR
      cnt.introtext LIKE '%%' AND 
      cat.alias LIKE 'something'
WHERE cnt.title LIKE '%%' OR
      (cnt.introtext LIKE '%%' AND cat.alias LIKE 'something')
WHERE (cnt.title LIKE '%%' OR cnt.introtext LIKE '%%') AND 
      cat.alias LIKE 'something'
WHERE (cnt.title LIKE '%".$conn->real_escape_string($trefwoord)."%' OR
cnt.introtext LIKE '%".$conn->real_escape_string($trefwoord)."%')
".$branchequery."

cakephp - building a query with a multi-word search string, searching multiple fields


By : Rope Liu
Date : March 29 2020, 07:55 AM
may help you . I have a model 'Mix' which has the fields (which I'd like to be searchable) 'name' 'description' and 'tag_words', as well as a boolean field 'published'. Users should be able to enter a multi-word search term and get results back for any of their words appearing in any of the searchable fields providing the 'published' field is set to 1 , You don't use the AND index, it is already implied:-
code :
$searchResults = $this->paginate('Mix', array('conditions' => array('Mix.published'=>1, 'OR' => $conditions)));

this one helps. I have the following code to search a grid of characters below from left to right to find a word. This works perfectly.
code :
if ((j+k <= board[i].length) || (letters[k] != board[i][j+k])) {
if ((j - k < 0) || (letters[k] != board[i][j-k])) {

MYSQL- Query to search using 'like' but searching only specific columns

This might help you You don't write multiple WHERE clauses, you write multiple conditions in the WHERE clause. (Exactly like your query already does with the two LIKE comparisons, though perhaps with some parentheses to specify the logic a little more explicitly.) Something like this:
code :
SELECT
  *
FROM
  tenders
WHERE
  (Heading LIKE '%{$key}%' OR Date LIKE '%{$key}%')
  AND status = 'online'

wish of those help Every data structure has it's value.
For instance, you'd use a binary tree most likely if you had numerically sorted data because your complexity would be really low (I.e. O(logn)).
