2.2. Search strategy
Based on both reputation and content coverage, we identified Pubmed, Embase, PsycINFO and relevant sections of The Cochrane Library as the key bibliographic
databases for our query. Our enquiry was constructed following to the PICO-method.1 Key elements that we used in our search were the ‘P’ (addicts/addiction
to drugs, food, alcohol and nicotine or individuals experiencing strong craving for food), the ‘I’ (rTMS or tDCS stimulation), the ‘C’ (Active and Sham
stimulation) and the ‘O’ (craving levels). To minimize the risk of bias, no limits were applied. For reasons of transparency and reproducibility, the complete
documentation of the search is included in Appendix 1 of this article.](https://image.slidesharecdn.com/20140129enhancingandexplainingsearchstrategiescitingreferences-140131015634-phpapp01/85/Enhancing-and-explaining-search-strategies-citing-references-12-320.jpg)

(i.e. PageRank) ?? ? ? ?? And what about: • content (first 1000 results limit) • … and (level of) evidence? Joost Daams – Medical Library AMC – 31 January 2014 So, what if your topic isn’t (exclusively) (bio)medical?
- 8. Enhance searching 2. Explore eligable sources of information (slide 3) - Browsing lists of available databases by provider (e.g. OVIDSP, Ebscohost, library system: AMC-Literatuur) - Using a discovery tool like PRIMO (http://lib.uva.nl ) - Looking up indexing of journals in unknown/other bibliographic databases (Ulrich’s serials directory: http://ulrichsweb.serialssolutions.com/ ) - Searching meta-registers of (Open Access) repositories (e.g. BASE: http://www.base-search.net/ ) Joost Daams – Medical Library AMC – 31 January 2014 Discover new sources apart from Google Scholar by:

- #10: Niet systematisch zoeken: Quick-and-Dirty Best match Werkt het beste bij toevoegen van meer en meer specieke termen Voordeel: + geschikt voor achtergrondvragen waarbij zoekconcepten moeilijk te definieren/scheiden zijn Nadelen: - Minder transparant en reproduceerbaar - overzicht van relevante informatie in 1 keer is onmogelijk Systematisch zoeken: Conceptuele zoekstijl, ontleding van de vraag in concepten met interne prioritering, is een combinatie van: Most unique concept first (meest specifieke aspect eerst) Successive Fractions (methode van opvolgende inperkingen) Interactive screening (Methode van interactief scannen) Operationele zoekstijl, betekenis van de vraag staat centraal, alle aspecten komen terug, is een combinatie van: Building Blocks (bouwsteen methode) Citation Pearl Growing (parel groei methode - in zekere zin valt deze onder de operationale zoekstijl, meer zie: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1175807/) Snowballing Meer info: http://www.library.uu.nl/medew/it/eric/informatie-zoeken.pdf http://www.zoeken-en-vinden.nl/index.php?page=retrieval-woordenboek
