Take into account fulltext maxSize when computing text in FulltextExtractorWork

            List<String> strings = new ArrayList<>();
            for (Blob blob : blobsExtractor.getBlobs(document)) {
                String string = blobsText.computeIfAbsent(blob, this::blobToText);
                strings.add(string);
            }
            // add space at beginning and end for simulated phrase search using LIKE "% foo bar %"
            String text = " " + String.join(" ", strings) + " ";
