Hello, I have a problem with the native search function of Prestashop. Every couple of days, the search index seems to become corrupt, which results in search results not being displayed correctly (might display 10 results out of 400, or it might not display anything). When that happens, I do a re-indexing of the search index, and the problem is solved, but a day or two later, the same happens and I have to do a full re-indexing again. I tried disabling the "auto-index new products" feature, and now I am just adding new products to the index by clicking on the link after I am done adding new ones, but the problem still persists. Any idea what I should do?
