Elasticsearch Implementation · London
Elasticsearch Implementation in London
Implementing Elasticsearch for London organisations, where the mapping is effectively permanent once an index exists. A field's type cannot be changed in place, so a decision made casually during setup — a date stored as text, a keyword analysed as free text — is corrected only by reindexing everything.
Why this comes up
The problem
A field was indexed with the wrong type, the queries that need it cannot work, and fixing it means rebuilding the index.
What you get
What we deliver
- Mappings defined explicitly rather than left to dynamic inference
- Analysers chosen for the language and the matching behaviour you need
- Index strategy planned, including aliases so reindexing is possible without downtime
- Time-based indices used where data ages, so retention is a deletion not a query
- Source of truth kept elsewhere, since reindexing requires the original data
- Query patterns tested against realistic volumes rather than a sample

London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.

Elasticsearch Implementation in London — common questions
- Why does dynamic mapping cause problems?
- Because it guesses from the first document it sees. A reference number that happens to look numeric becomes a number, a date arriving in an unusual format becomes text, and the resulting mapping is fixed before anyone has reviewed it.
- How do we change a mapping?
- By creating a new index and reindexing into it, then switching an alias. Using aliases from the start makes this a routine operation rather than an outage — which is why they are worth setting up before you need one.
- Should it be our primary datastore?
- Generally not. It is a search and analytics engine rather than a system of record, and reindexing — which you will need — requires the original data from somewhere. Keeping the authoritative copy in a database makes both roles work properly.
- Why use time-based indices?
- Because deleting an old index is instantaneous while deleting documents by query is expensive. For logs, events and anything that ages out, rolling indices turn retention into dropping a whole index rather than a large ongoing deletion workload.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
