Initially, I developed this deals alert service for my personal use and later on thought it might be
useful for others too, so I extended it accordingly and added it here. This service basically grabs RSS feeds from deals sites (listed on the deals alert page of my site) and checks for
the keyword(s) that are added, and if it finds a match, sends email at the time mentioned on the page. This service performs properly only if the keyword(s) are specific, because it is
just using some ‘exact’ and ‘like’ string searches. I might be
improvising this by using dictionary or thesaurus in the future. You can
enter multiple keywords (separated by spaces) related to a single product, and only if all the words
are present on the deal title, alert email will be sent. As I’m just using simple
search here, the deal may not be related to the product you are looking. For
eg., say suppose you add an alert for ‘card reader’ and if there is any deal for
a laptop with ‘card reader’, my service is going to grab this deal too, because this
service is not as intelligent as you are :). So, in this case it is better to
add price limit too.
added this service without any commercial intention, so do not worry about your
emailids, I won’t trade them to advertisers, and moreover you can unsubscribe
from this service or modify the added keywords at any time by clicking
‘Unsubscribe’ link on the email that will be sent to you after adding an alert.
writing this service I understood how difficult it is come up with search
algorithms, hats off to Google and other search engines. Implementing ‘exact’
keyword search was easy whereas ‘like’ search was very difficult. For eg., I added ‘backpack’ as keyword, the
service was bringing all the deals having ‘pack’ on the title, like ‘cd pack’,
‘dvd pack’ etc. I told about this service to couple of my friends, and one of
my friends added ‘mens watches’ as keyword, and found out that most of the
deals had “men’s” on the title. I recoded to accommodate this scenario, but still it is going to bring deals related to women's watch even if you add men's watch. One
last example, keyword ‘all in one printer’, there was a deal with title ‘Calls
to any phone in India’, if you see here ‘all’ is in ‘calls’, ‘in’ is in ‘India’
and ‘one’ is in ‘phone’. I can keep listing out examples on this service's ability/disability. As a developer, I have done my testing part (developer's test cases are always subset of testers' test cases) to an extent, it is yours now...you are my testers!
have any idea or thoughts to improvise this service, please send your comments.
