    <p>Although I generally agree with shoosh's answer, his approach makes it easy to achieve high recall but also low precision, i.e. you would get almost all real words but also a lot non-words. If your definition of word is too restrictive, it's the other way around but that's also not what you want since then you would miss cases like 'zebra123'. So here are a few ideas about how to improve precision:</p> <ol> <li><p>It may be worthwile thinking about if you could determine what parts of an email belong to the main text and which are footers like pgp signatures. I'm sure it's possible to find some simple heuristics that match most cases, e.g. cut of everything below a line which consists only of '-'-characters.</p></li> <li><p>Depending on your performance criteria you may want to check if a word is a real word or contains a real word by matching against a simple word list. It's easy to find quite exhaustive lists of Englisch words on the web, and you could also compile one yourself by extracting words from a large and clean text corpus.</p></li> <li><p>Using a lexical analyser, you could filter every token which is marked as unknown.</p></li> <li><p>Some simple statistics may tell you how likely it is that something is a word. Tokens which occur with high frequency most probably are words. Tokens which appear only once or whose number is below a certain threshold very probably are not words. Common spelling errors should appear more than once and uncommon ones may be ignored.</p></li> </ol> <p>Some if these suggestions clearly don't work for cases like 'zebra123'. Again, simply cutting off, or splitting on, in-word numbers may do the trick. </p> <p>My general approach would be to first identify tokens which certainly are words (using the suggestions above), then identify tokens which certainly are not words (using a regular expression), and then look (with your eyes) at the few hundred or thousand remaining tokens to find common characteristics to handle these separately.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
