Gartoo HOWTO

• Queries are analysed using Nestoria/Lokku::NLP
• Handles '2 bedrooms' and strips out stopwords
• Checked against LME (Link Management Engine (?))
• SERP is constructed by Lokku::Gartoo::Search::ListingSearcher
• Scoring/sorting is done by passing Sphinx algorithm

Gartoo

Matches are highlighted

Gartoo

Only results matching all terms are returned

Nestoria

Returns matches from full_description/keywords

Not obvious why listings are matched

Nestoria

Lots of filtering options

Bilatu

Not so much

Nestoria 'free text search'

Requirements ?

Requirements

• Allow Free Text Searches
• Provide cross links to 'similar' searches
• Run alongside current SIM/geo searches

BIG Open Questions

Limit to geolocatable areas?

• Will simplify architecture
• If we don't, what do we do with the map

BIG Open Questions

Concurrent old/new searches

• How do we allow the user to do geo searches AND free text
• Two search boxes?
• Do we (frontend) know at search time which is occuring

Text

BIG Open Questions

Localdata/Metadata/Facets

• This is very specific SIM code
• Replicating will take time

BIG Open Questions

Deduplication/Scoring

• SIM specific functionality
• Backend databases do not support deduplication as we know it
• What does Gartoo do?
• If we keep our current architecture, this will mean running 2 simultaneous SI builds
• Syncing out twice as much data on each build

BIG Open Questions

Hardware

• We will run alongside our current site
• Gartoo currently uses 4 servers for a low throughput site (?)
• How many extra servers are we expecting?

Small Open Questions

URL formats

• What formats are we expecting

/london-flat-rent-balcony

/houses-in-london-with-gardens-and-a-swimming-pool

/I-totes-loves-Nestoria-init

Small Open Questions

How do we search?

• Match some or all terms?
• Handle '2 bedroom' type queries?
• Match against what? (full_description/keywords/address)
• Aim to highlight results in SERP?

Architecture

Build new 'search-api'
