The aim is to harness the power of boolean logic, which is useful in searching in library collections, as well as to have a little fun. For this game, you will take the role of (text-color:white)[detective Schou,] a veteran of the force. You must first find the clues, note them down in your trusty notebook, and then combine them to narrow down the suspects using Boolean operators. While the game is meant to demonstrate how these operators work in an intuitive way, you can also read this short overview before getting started: [[Boolean overview -> Boolean overview]] Or you can [[get on with the story. -> Detective intro]] [[Credits]]]

(font: "Garamond")[Boolean logic was developped by a 19^^th^^ century mathematician named George Boole.] <style> img { max-width:100%; max-heigh:100%; } </style> <img src=https://live.staticflickr.com/65535/54365408815_753f695790_b.jpg> </div> (font: "Garamond")[He had some wild ideas about the logic that he developed but its lasting influence has however not been in the field of philosophy but in computer science as well as library and information science. Boolean opperators have been harnessed in digital library collections to help specify searches in a database. You can use these opperators to modify a search for litterature (or criminals!). Here's a list of a few of them, as well as a few other search tricks;] (font: "Courier New")[*AND] (font: "Garamond")[: ] (font: "Courier New")[ AND ] (font: "Garamond")[stipulates that a given item must contain what you specify before and after the opperator. So for example the search "chocolate AND ice-cream" would contain hits that include both chocolate and ice cream, but would filter out those that only included one of those terms (no chocolate cakes or vanilla ice cream, for example). AND is therefore particularly useful to narrow a search down if you are getting a lot of hits.] (font: "Courier New")[*OR] (font: "Garamond")[: ](font: "Courier New")[ OR ] (font: "Garamond") [stipulates that either item from a pair will return a hit. Note that all items that contain both will also be included. This is a great way to cover a number of different synonyms or terms that to an entity, which is semantically similar. This way you can broaden your search] (font: "Courier New")[*NOT](font: "Garamond")[: ](font: "Courier New")[ NOT] (font:"Garamond")[ stipulates a term, that should not be included. This can be useful if a single term has multiple semantic meanings (polysemy). A good example is the term Mercury, which can refer to a metal, a planet, a Roman god, and a defunct American car company, not to mention the poetic licenses of the word ("the mercury is rising..."). NOT can cut out unwanted noise in your search.] (font:"Cursive")[Hot tip!] (font:"Garamond")[Using an asterisk after a certain term will pull all items that have the written element plus anything else that follows. For instance, a search with the asterisk following wom* will return items that include woman, women, womyn, womanly, women's etc.] [[Back to menu ->Introduction]]
