“Funnelback has taken our complexinternal information environment andmade it accessible”

Mike Swanson, OxfamKnowledge and Information Services Team Leader  

“Search is life”

Costs of poor search• Butler Group: Up to 10% of salary costs

wasted through ineffective search• IDC: A company with 1000 information

workers can expect to waste more than $5M p.a. due to poor search

• Accenture: A survey of 1000 middle managers spend as long as 2 hrs/day searching for information.

Who's the SearchMaster in your organisation?

Stakeholders expect every SearchMaster to do her duty!

• To make external website search work– Sales conversions– Information dissemination– Reduced inquiry handling load

• To provide effective search of corporate information– Happy, productive employees (plus students

and other stakeholders)

Give them the tools and they will do the job!

• Searchmaster• End-user

• Simple• Powerful

1. The basic search tool• Coverage and scale• Quick and easy to install• Good out-of-the-box performance

– It can find the answers people want

• Simple to configure– Avoid features which are too complex to use or

set up.

Time to set up Funnelback• As little as a couple of minutes to install the

product.• As little as a couple of minutes to create a

collection and start updating• A couple of hours to customise look and

feel• A few minutes to activate contextual

navigation, faceting and featured pages.

Perceived Funnelback advantages

• Tried and tested algorithm (20 yrs dev.t)• Control from admin interface• Customisability of business logic / Open

APIs• Flexible result presentation• Professional services model• Open published price list

2. FineTuning• Every search deployment is different

– Web, database, fileshare, Lotus

• The weighting of ranking features must accommodate to the differences

• Manual tweaking is fraught with danger– Fix one query, break a dozen

• Make a test file and use Funnelback FineTune

Testfile Desiderata• Representative of real workload

– Unbiased sample– Good estimate of actual performance– Best tuning

• Many queries (e.g. > 100)• Multiple weighted answers (where

applicable)

Other LSE Testfiles• Click logs – Right answers are those that

users clicked– Possible to tune to 0% failure rate (unrealistic)

• From keymatches file created for previous search technology(it had 709 rules)– Failure rate is higher (unrealistic)

• Random sample is the preferred approach

FineTuning Summary• Tuning 38 dimensions• Millions of query executions• Achieves substantial gains• Contact support@funnelback.com

But why do some queries still fail?

• Misspelled– Westminister Abbie

• Query words don't match language– “door” or “MOPEM” v. “manually operated

personnel egress mechanism”

• There is no answer to that question.– Maybe there should be– Scope issue?

• How information is published.

Need more tools!

3. Spelling suggestion tools• Suggestions may be useful even if words

are correctly spelled:– Carlton furball club → Carlton football club

• Suggestions based on whole query, not word-by-word

• Don't suggest queries which make no sense in the collection being searched

• Autocompletion: Guide users to the best query

• Context is king

4. Query expansion tools• Manual rules:

– Rego → [registration rego]– MOPEM →[“manually operated personnel

egress mechanism door”]

• Related queries (automatic)– Based on co-clicking

• Contextual navigation (on-the-fly)– Finding superphrases in a deep result set

• Faceting (semi-automatic)

Related queries

Tools to tell you when you need to add, change or reorganize content.

5. Reporting Tools• Queries that produced no results• Click patterns that suggest user wasn't

happy• Pattern analysis – query spike

Conclusions• Search is important

• Organisations benefit when someone takes responsibility for effective search – the SearchMaster.

• A good search tool provides a full kit of simple, effective tools to help the SearchMaster achieve just that.
