Subject: [PATCH 1/8] test(web): add a rank check for the docs search

Bumping fumadocs from 16.15 to 16.17 changed where pages land in
/api/search, and nothing in the repo could show it. The script asks one
or more running builds of apps/web for a fixed set of queries and prints
the rank of the page that documents each one, so two builds can sit side
by side in one table.

On the parent of the bump (77a4430) against main (a6f431b):

| query     | page                     | 77a4430   | a6f431b   |
| --------- | ------------------------ | --------- | --------- |
| filter    | /docs/core/filters       | #1 of 94  | #32 of 60 |
| upsert    | /docs/core/store         | #1 of 34  | #30 of 33 |
| eq        | /docs/core/filters       | #1 of 36  | #10 of 33 |
| namespace | /docs/guides/migration   | #1 of 82  | #10 of 60 |

Subject: [PATCH 2/8] fix(web): index docs table cells one by one again

fumadocs-mdx 15.4.7 with fumadocs-core 16.17 records a table as one
record per row, each carrying the header row, and drops the record per
cell that 16.15 made. Those row records are long, so BM25 scores them
below the short headings of other pages, and the page that documents an
API name in a table cell falls down the results. The Filters page went
from #1 to #32 for `filter`, and the Store page from #1 to #30 for
`upsert`. Before the bump, `not(filter)` in a Filters table was a
three-token record that tied with the best heading on the site.

The `types` option of `remarkStructure()` decides what becomes a record.
Putting `tableCell` back in the list, in place of `table`, yields the same
records per page as 16.15 (72 for filters, 58 for store, and so on).

Search ranks of the page that documents each query, at 77a4430 (before
the bump), a6f431b (main) and this commit:

| query     | page                    | 77a4430   | a6f431b   | this      |
| --------- | ----------------------- | --------- | --------- | --------- |
| filter    | /docs/core/filters      | #1 of 94  | #32 of 60 | #1 of 60  |
| upsert    | /docs/core/store        | #1 of 34  | #30 of 33 | #1 of 34  |
| eq        | /docs/core/filters      | #1 of 36  | #10 of 33 | #1 of 36  |
| namespace | /docs/guides/migration  | #1 of 82  | #10 of 60 | #1 of 60  |
| namespace | /docs/providers/upstash | #38 of 82 | #1 of 60  | #38 of 60 |
| qdrant    | /docs/providers/qdrant  | #16 of 43 | #1 of 57  | #1 of 43  |

The qdrant gain stays. It shows with the 16.17 search server on the
per-cell index, and with the row index on the 16.15 server, so it does
not depend on row records.

Subject: [PATCH 3/8] fix(web): drop the table pipes from search results

With cells indexed one by one, fumadocs slices each cell from the
Markdown together with the pipe that opens it, and the last cell of a row
with the pipe that closes it. The search dialog renders that Markdown, so
results such as `eq(field, value)` showed up as `| eq(field, value)`.

Strip an opening pipe and an unescaped closing pipe from every record
when the index is built. A pipe escaped with a backslash inside a cell is
kept. Ranks are unchanged, a pipe is not a token.

Subject: [PATCH 4/8] test(web): rank the docs search by page, not by result
 index

The search lists a page followed by its hits, and the dialog groups them the
same way, so what a reader sees is the order of the pages. A page that sits
fifth in the dialog was reported as #28 because the four pages above it
contributed up to eight hits each, and the number grew or shrank with how many
records matched elsewhere.

Report the position of the page among the distinct pages instead, and list
pages rather than records under --top.

Subject: [PATCH 5/8] test(web): probe provider names and queries that never
 regressed

The rank check only covered the concept queries, so a fix for them could move
the provider pages without anyone seeing it. Measured on the builds before #61
and on main, a provider name that is also a column header in the comparison
tables ranks its page between first and fourth: `vectorize` and `upstash` sit
at #4 before the bump, and `supabase` slips to #2 on main.

Add the seven provider names, and `createIndex`, `topK`, `install` and
`delete` as guards for queries nothing was meant to change.

Subject: [PATCH 6/8] fix(web): rank a page title above equal-scoring table
 cells

The advanced search indexes every record into one `content` field, so a page
title weighs the same as any sentence and BM25 favours the shorter record.
A column header in a comparison table is a one-word record. For `pinecone` it
is the same word as the title of the Pinecone page and ties with it, and the
tie goes to whichever page was indexed first. For `vectorize` and `upstash` it
beats a two-word title such as `Upstash Vector`. Measured on the built site,
these provider pages sat at #4, and #4 is also where they sat before #61.

Fumadocs' simple search boosts the title field for this reason, but the
advanced search takes no per-field boost. It does take a `sortBy`, so scale
the score of a page record by 1.5 before sorting. Every probe ranks the same
for any factor from 1.1 to 4, which is why the value is not tuned further.

Drops the seven provider queries from #4 to #1 and leaves `filter`, `upsert`,
`eq` and `namespace` where the previous commit put them. Stemming does not
help here: the English stemmer turns `vectorize` into `vector`, which matches
most of this site. Row-level table indexing with the same boost still leaves
`upsert` at #10 and `eq` at #3, so the per-cell types stay.
