Though a more basic searching technique, keyword searches allow professionals to identify one or two specific words from multiple documents. Nowadays, keyword searches are considered inferior to the successor, predictive coding (TAR). In comparison to TAR, the “outdated” search method is more expensive and time-consuming. Keyword searches are also less predictable; when filtering through the same data set, keyword searches yield fewer results. Based on these flaws, some would argue that keyword searches are a dying technique.
