![]() ![]() The fields to include will likely be dimensions and perhaps not much else. Result and recommendationĪ very small amount of time is added to the end of the reload while only the included fields in the data model are indexed for Smart Search. Note that the syntax for including and excluding fields enables you to use wildcards when referring to field names. SEARCH EXCLUDE How to include only certain fields SET CreateSearchIndexOnReload = 1 Refine which fields are indexed for Smart Search How to exclude only certain fields SET CreateSearchIndexOnReload = 1 And of course you can disable it during development, before you publish. Some Qlik solutions may not expose the global search bar at all, like mashups, embedded solutions, or custom web apps, so there may be no cost to disabling it in those scenarios. While tiny, this would be wasted compute for whatever metadata is in the QVD generator’s data model. ![]() We disable search indexing on reload in all our QVD generators, as a standard practice. While this is generally a bad combination of outcomes and one we do not recommend for a typical user-facing application, it can sometimes be appropriate to disable. The searches may also take longer and there may be more noise in the results because every field was indexed. When the first user attempts his or her first search, they will wait for the indexing to happen. No time is added to the end of the reload for search indexing. Delay indexing until the first search is executed How to implement SET CreateSearchIndexOnReload = 0 Result and recommendation Users can get immediate results, but search may take longer and there may be more noise in the results because every field was indexed.įor small-to-medium data sets, this may be perfectly fine. Some time is added to the end of the reload while all fields in the data model are indexed for Smart Search. When you create a new app, this variable and value are already set, by default, in the system variables. Index everything on reload How to implement SET CreateSearchIndexOnReload = 1 Index during reload, but only included fields ![]() Regardless of search indexing settings, you can still search and filter by any field individually in dimensions, filter panes, or the selection pane. ![]() The search index built at the end of the reload applies only to the Smart Search at the top of the user interface. But instead of this blunt method for speeding up reloads, let’s focus on speeding up search indexing, which also speeds up reloads, speeds up Smart Searches, reduces noise in search results, and prevents users from having to see the search indexing progress bar.ĭisclaimer: if your data aren’t large (10s of millions or rows+) and frequently reloaded (many times per day), don’t worry about search indexing time, unless you’re a perfectionist. The explanation is inevitably that the developer wanted to shorten the reload time, and search indexing was adding time at the end of a reload. Why handicap this Qlik differentiator by disabling building the index during the reload? Why make me wait? This isn’t a feature of the software or how it was intended to work, but the result of a developer’s decision to disable search indexing on reload. An occasional experience I have using large Qlik Sense applications is typing in the global search bar (AKA Smart Search) and waiting, while a progress bar says Qlik is preparing Smart Search. ![]()
