Search records are stored in the local cache.
After searching in the mobile browser, the search record will be saved in the local cache. Even if the browser cache and history are cleared, the search history in the local cache will not be cleared. Therefore, even if the browser cache and history are cleared, the search history still exists.
Search records are saved in the cloud account.
In addition to the local cache, some mobile browsers also save search records in cloud accounts. This means that even if you log in with the same account on different devices, the search records will be synchronized to other devices. If you want to completely delete the search record, you need to delete it in the cloud account.
Search records are kept by the website.
Some websites will save the search records on the server after users search. This means that the search history still exists even if the browser cache and history are cleared. If you want to completely delete the search record, you need to delete it in the corresponding website.
Generally speaking, there are three reasons why the search records in the mobile phone webpage cannot be completely deleted: the search records are saved in the local cache, saved in the cloud account, and deleted by the website. If you want to completely delete search records, you need to be clear about these three aspects. Of course, you can also use some third-party software to help clear the search records.
