Why is a poorly formatted filter a common issue?

A poorly formatted filter is often a common issue because it requires an exact match in the log. This means that if the syntax or structure of the filter does not closely correspond to the entries in the log files, it may fail to yield any results, or it might miss relevant entries entirely. Filters typically rely on precise parameters to sift through extensive data logs effectively, and any deviation from the expected format can lead to ineffective filtering, making it challenging for users to obtain the insights they require.

Meanwhile, while it might seem logical to think that formatting might default to no results, that isn't always the automatic response when a filter is ill-constructed. Filters might still retrieve some data, albeit not necessarily the desired data. Although performance issues can arise from complex or non-optimized filters, a poorly formatted filter primarily hinges on the need for exact matching criteria. The option concerning saving the filter pertains more to user interface and usability aspects rather than the foundational issue of format.
