There are several categories of search engine software: Web search or full-text search (example: Lucene), database or structured data search (example: Dieselpoint), and mixed or enterprise search (example: Google Search Appliance). The largest web search engines such as Google and Yahoo! utilize tens or hundreds of thousands of computers to process billions of web pages and return results for thousands of searches per second. Searching for text-based content in databases or other structured data formats (XML, CSV, etc.) presents some special challenges and opportunities which a number of specialized search engines resolve. Database search engines were initially (and still usually are) included with major database software products. In more advanced Database search systems relational databases are indexed by compounding multiple tables into a single table containing only the fields that need to be queried (or displayed in search results).

List of academic databases and search enginesFrom Wikipedia, the free encyclopedia This article contains a representative list of notable databases and search engines useful in an academic setting for finding and accessing articles in academic journals, institutional repositories, archives, or other collections of scientific and other articles. Databases and search engines differ substantially in terms of coverage and retrieval qualities. Users need to account for qualities and limitations of databases and search engines, especially those searching systematically for records such as in systematic reviews or meta-analyses. As the distinction between a database and a search engine is unclear for these complex document retrieval systems, see: the general list of search engines for all-purpose search engines that can be used for academic purposesthe article about bibliographic databases for information about databases giving bibliographic information about finding books and journal articles.

Websearch: Habits of the mindIn het kader van mijn online-traject “Essenties in de praktijk, stel ik me steeds meer nieuwsgierige vragen rondom de essentie: je gebruikt je hersenen goed. Vraag me af als je je hersens goed gebruikt, welk gedrag/gewoontes ontwikkel je dan. Moest denken aan de webpagina van essentieel leren rondom de 16 habits of Mind. En ben gaan grasduinen. Ik hoorde hier de schrijver aan het woord. Ik onthoud: “skills and strategies that a person might use when confronted with problems the answers to which are not immediately known” Hier vond ik deze prachtige visualisatie. Op deze webpagina legt in een video professor Costa alle gewoontes uit. Ik ben ze mbv de Yurls allemaal even “langsgegaan”. Helder en precies denken en communiceren. Enfin, ik zie de gewoontes nu wel voor me. Ontwikkelingen na het publiceren van deze post. @Ilsemeelberghs In Pearltrees had ik ook al wat verzameld rondom “Habits of mind”
Using The Habits Of Mind To Promote Teacher Happinessby Arthur L. Costa and Bena Kallick, Institute for Habits of Mind A Whole Child Deserves A Whole Teacher: Using The Habits Of Mind To Promote Teacher Happiness A lot is said and written about the whole child. We often forget, however, that we should be considering the whole adult as well. These are the questions that arise as teachers work in their classrooms every day. To develop the whole child, teachers need Habits of Mind that help them problem solve, become better critical thinkers, and communicate– to become whole teachers who manage their social, physical, emotional, and cognitive skills as they respond and interact with their students.
