There is only one ad in my site ( https://www.lkdoctors.com/oc/search/sOrder,dt_pub_date/iOrderType,desc/iExtra,1/pattern,Example+Ad)

ad name is Example Ad.
But when i search it(keyword as Example Ad)  in above search page it doesn't show any result.
Help me

@unlimit
Link you've sent did not return any listings as well. Reason can be that there is no description/title for that listing in your language, anyway theme has no impact on search functionality.

When i search "Mitshubishi" it shows results.
But when i seach "Mitshu" no results

i want to search by 4-5 letters

It is full text search that osclass use. Check documentation.

Same i am looking at as search needs to be at least 3 characters and partial word search also is fine.

Where can we tweak this setting? Also, it needs to cover the description text as well.

Do direct us to the file name, we will get the changes done as half of our results are no result found

e.g. QV1 (Queen Victoria 1) KGV (king George 5), WW2 (world war 2), IND (India) and so on what people will search
