OPAC search cloud and failed searches

Seeing as I’ve got my head in the clouds at the moment, here’s one showing the most popular keyword search words used on our OPAC during the last 6 months…

To be honest, there aren’t too many surprises in there — students studying business & law and the health sciences are the heaviest users of the library.
Unlike Yahoo, not a single person has done a search for “Britney” on our OPAC in the last 6 months …and “yes”, you would get a relevant hit if you did 😉
I’ve also separated out words that appear in failed keyword searches (i.e. they produced no hits) and removed those which did appear in other successful searches — this gives a list of keywords that probably don’t match anything on the catalogue:

  1. newspapermen (96)
  2. socail (90)
  3. buisness (84)
  4. brantingham (74)
  5. renew (74)

  7. reserach (72)
  8. mortor (67)
  9. vehclos (66)
  10. gieber (63)
  11. thoery (63)
  12. writting (62)
  13. psycology (59)
  14. contempory (58)
  15. donky (51)

  39. theorys (32)
  40. enviromental (31)
  41. pschology (31)
  42. statistic (31)
  43. syringe (31)
  44. hanbook (30)
  45. simnet (30)
  46. stratergy (30)
  47. intoduction (29)
  48. pestel (29)
  49. physio (29)
  50. pratice (29)

The words in bold are valid spellings (according to Microsoft Word) and the figure in brackets is the number of separate searches that contained the word.
Compared to the cloud, this is much more interesting…
1) many of them are simple typos — another good reason to add a spellchecker to your OPAC if you haven’t got one!
2) the fifth most common word is “renew” — are our users trying to renew their books by typing the word into the OPAC, or are they expecting the OPAC to work like a search engine and return something like “How to renew your books” as the first result?
3) the sixth most common word is “metalib” — it looks like a lot of people are trying to find help on using MetaLib in the OPAC… maybe we should create a dummy catalogue record that contains 856 links to MetaLib and our Electronic Resources Wiki?
4) “mortor” is an oddity in the list… but the entry for “pestel” near the end makes me wonder if people were searching for “mortar and pestle”?
Outside of the top 50, there are some other interesting failed keywords (with links to Wikipedia or other sites when relevant):
