search

Think inside the box. Inside the search box, that is.

The "best"* search results incorporate many more factors than (just) textual matching and relevancy. Search experience owners manage query context rules, signals automatically feed back machine learned factors, users implicit and explicit behaviors filter and weight future interactions. Synergy emerges with several cooperating (just) searches.

This talk will showcase and detail several (just) search examples including rules, typeahead/suggest, signals, and location awareness, bringing them all together into a cohesive search experience.

Highlighting

Grouping

• relevancy ranked results

• faceting

• highlighting

• grouping (collapsing)

• more-like-this

• did-you-mean (spellcheck)

Search Features

typeahead, autocomplete,

suggest, instant search

spell checking

• query a “typed” n-grammed index, and get “typed” results

• type examples: brands, categories, specialties, treatments, providers/doctors, products

• suggest Things Not Strings

• things have attributes: metadata

(known) entity detection

• /select?q=sea…

• q=<what user typed>

• Response includes grouped and ranked results, highlighting, and spellcheck suggestions

typeahead request

signals

• clicks and queries

• add-to-carts

• user history, behavior, and preferences

• geo-location, device

signals and recommendations

signals workflow

• <collection>/select?q=search

• <collection>_signals_aggr/select

• ?q=${q}

• qf, pf, sort

• ==> bq: "id:7^1.0"

signals sub-query

rules

• trigger off query context

• query, filters, date/time, tags

• actions -

• boost, block, banner, redirect, set parameters, rewrite query, etc

• superset of signals

• signals: automated feedback

• rules: manually created

rules

• <collection>/select?q=solr search[&tags=mobile,production]

• <collection>_rules/select

• ?q=${q}

• &fq=-enabled:false

• &fq=…effective_range:$now…

• &fq=…tags:($tags)…

• process rules returned

• manipulate request, append to response

rules sub-query

geo-lookup

• /providers/select?q=jones&zipcode=10301

• /zipcodes/select?q={!term f=zipcode_s v=$zipcode}
